Chromojet vs Colaris Digital Carpet Printing: Auditing Dye Penetration for Hospitality Contracts

## Chromojet vs Colaris Digital Carpet Printing: Auditing Dye Penetration for Hospitality Contracts

When you specify printed carpet for a hotel, cinema, or airport, the print head that put color on the yarn matters as much as the fiber itself. Chromojet and Colaris are the two Zimmer Austria systems most Indian mills will quote you. They look similar on a factory tour. They are not similar on a busy corridor two years later.

Chromojet is a jet-based spot color system built for deep dye penetration and high-volume wall-to-wall work. Colaris is a piezo inkjet system built for high-resolution process color, fast design changes, and lower ink waste. Both can print polyamide and wool tufted carpets. Both can fail a hospitality contract if nobody audits penetration, dye lots, and pile consistency before the container leaves India.

This guide is for importers, hospitality buyers, interior designers, and private label brands who source from India and need the print to survive real traffic, not just a showroom light. If India sourcing is already on your list for hospitality flooring, print technology belongs in the first conversation, not the last.

What dye penetration actually means on a contract carpet

Dye penetration is how far color travels down each tuft. Surface print looks sharp on day one. After vacuuming, rolling luggage, and wet mopping, the tips wear. If the dye stopped halfway down the pile, you get frosting, shade shift, and complaints from the general manager.

For high-traffic areas you want color that reaches the backing, or as close as the construction allows. That requirement is why Chromojet still dominates commercial wall-to-wall in India, even as Colaris wins more decorative and short-pile work. Industry coverage on menacovering.com notes that jet-based Chromojet systems remain the lead choice for hotels, airports, banquet halls, and cinemas because of deep dye penetration, chemical resistance, and long-term durability.

You should still test Colaris goods the same way. Zimmer positions Colaris with inline pre-treatment and full penetration on the constructions it is designed for, especially shorter pile. The audit is the same. The pass or fail standard should be written into your purchase order, not left to the mill's judgment.

Chromojet: spot color, deep jets, commercial volume

Chromojet (often written CHROMOJET) fires relatively large dye jets in spot colors. Mills typically run 8 to 16 colors on production lines, and more on logo-mat machines so they do not keep swapping shades. The popular production frames are Chromojet 200 and Chromojet 400 from Zimmer Austria, as discussed in industry comparisons on texintel.com.

What you get from that setup:

• Strong penetration on high-pile and structured carpets
• Durable coloration for heavy commercial wear
• High-volume wall-to-wall output
• Spot colors mixed in a color kitchen, which means paste preparation, recipe control, and wash-down between some changes

The trade-off is speed of design change. You work with a set of feed colors, not an open process-color mix. Fine photographic detail is not the point. Consistent, deep, wear-resistant color is the point. For corridor rolls, banquet halls, and cinema flooring, that is usually the right goal.

Chromojet also asks more of process control. If the color kitchen is sloppy, you get lot-to-lot drift. If jets are poorly maintained, you get streaks. Supplier verification has to include the print line, not only the tufting hall.

Colaris: process color, high resolution, fast changeovers

Colaris (often written COLARIS) is Zimmer's piezo inkjet platform, introduced as a new generation in 2008. It prints from 4, 6, or 8 base colors mixed on the carpet, closer to a large industrial version of a desktop inkjet. Reports on news.textileexcellence.com put resolution from 400 x 400 up to 400 x 1,600 dpi, against Chromojet's coarser jet pattern in the 25 to 76 dpi range. There is no system wash between design or color changes, and almost no ink wasted on leftover paste.

ategroup.com describes Colaris for short-pile carpet printing, high-resolution inkjet up to 1600 dpi, and ink usage in a 10 to 200 GSM range. No color kitchen is required. Thickeners are applied separately. The system is used on polyamide, polyester, wool, and acrylic carpets and mats, plus needle felt. The application range includes rugs, wall-to-wall, tiles, mats, runners, logos, promotion mats, and contract hospitality goods.

What you get:

• Fine detail and intricate decorative designs
• Rapid job changes and short runs without paste waste
• No limitation on pattern repeat in the digital file
• Lower operational waste
• Full penetration claimed on all colors when the process is set correctly, especially on shorter pile

Colaris is the better fit for event carpets, promotional flooring, custom logos, and rooms where the design does the selling. It is not automatically the better fit for a 2,000-room corridor package. Several Indian producers still tell buyers that Chromojet, not CMYK-style digital, is the safer call for heavy commercial wall-to-wall. That view is recorded in menacovering.com. Treat it as a starting hypothesis, then prove it on your construction, your pile height, and your wear test.

Indian Textile Journal has also noted growing Colaris adoption, with some Chromojet lines being replaced where the order book shifted toward higher resolution and shorter runs (indiantextilejournal.com). Your mill mix in India will include both. Your specification should name the machine family, not just digital print.

Side-by-side: what you should put in a spec

Zimmer's product pages on zimmer-austria.com treat the two as complementary for tufted polyamide and wool carpets, from broadloom to tiles, with layouts customized to the end product. textilegence.com makes the same split: Chromojet for industrial penetration and volume, Colaris for detail and fast job changes.

Do not let a mill sell you digital as a single category. Write Chromojet or Colaris into the tech pack, then lock pile height, fiber, and a penetration test method.

How to audit dye penetration before you approve bulk

A hospitality contract should not rest on a mill photo. You need a written audit that a third party can repeat. Here is a practical sequence you can require on India-made printed carpet.

1. Lock the construction first.Pile height, pile weight, gauge, stitch rate, fiber (nylon or wool), and backing. Penetration that looks fine on a 6 mm cut pile can fail on a 12 mm structured loop. Chromojet is usually the safer default on taller or structured pile. Colaris is usually the safer default on short pile and graphic work. Confirm with a sample on the actual construction, not a substitute quality.

2. Approve a production-intent sample, not a lab toy.The sample must come off the same print line, same ink set, same pre-treatment, same steaming and washing. Colaris uses liquid colors mixed on the fabric, which removes pre-mixed pastes, as explained by gdmats.eu. That is efficient. It also means a hand-painted strike-off is worthless as a production proof.

3. Cut the tuft and look.The oldest check is still the most honest. Cut a tuft or a small cross-section. You want color well down the yarn. Photograph it under consistent light. Compare dark shades and pale shades separately. Pale grounds often penetrate worse. If the mill only shows you the face, you have not audited penetration.

4. Wet and rub.Hospitality carpets meet wet mopping and spilled drinks. Require colorfastness to rubbing (dry and wet) and to light. Dye lot checks against the approved standard should happen before bulk dyeing or bulk printing, then again on finished rolls. A lobby that looks correct under factory tubes and wrong under warm hotel lighting is a classic miss.

5. Wear simulation on dark and light areas.Ask for a wear or traffic simulation on both the printed motif and the ground. Surface-only print will chalk or frost first on the high points of a sculptured pile.

6. Check lot continuity across rolls.Hotels order corridors in many rolls. Shade must hold from roll 1 to roll 40. Chromojet's color kitchen can drift if recipes are not controlled. Colaris can drift if heads or RIP settings change mid-run. Your quality control plan should include in-line shade checks, not only a pre-production sample.

7. Inspect before the container is sealed.Pre-shipment inspection should re-check pile height, print registration, penetration on retained cuttings, and packing. For multi-property hotel programs, this is not optional. One bad dye lot can land in three cities.

Indian producers running Zimmer lines do report consistent color and speed when the machines are well kept. That is the testimony in textileinsights.in. Your job is to verify that the specific factory quoting you is one of those producers, not a trader relabeling someone else's output.

India realities: where the print lines sit, and what goes wrong

India is a serious origin for both woven and tufted contract carpet, and for digitally printed hospitality goods. Clusters around Bhadohi, Panipat, and Jaipur cover different constructions. Digital print capacity is concentrated at mills that invested in Zimmer Chromojet or Colaris, not at every tufter who lists custom design on a directory.

What goes wrong when you buy remote:

• A trader quotes Colaris-level detail, then places the order on an older Chromojet with a coarse jet and hopes you will not notice on a phone photo
• Pile height on bulk is lower than the sample, which changes both hand and apparent color
• Dye lots shift after the first container
• Lead times were sales numbers, not machine calendars
• Export documents are incomplete, and the HS classification for carpets is guessed

Unverified supplier directories encourage all five. Middleman price inflation hides the real mill, so you cannot audit the print line. Uninspected production runs are how a beautiful sample becomes a mottled corridor. Misleading lead time promises are how a hotel opening date gets missed.

A buyer-side partner in India exists to stop that pattern. You need someone who walks the print hall, reads the machine plate, and holds cuttings from the actual bulk.

What Netyex does differently on printed carpet programs

Netyex is a dedicated sourcing partner and procurement office in India. We work for you, the importer, wholesaler, retailer, brand, designer, or hospitality buyer. We do not work for the factory. That single fact changes the audit. That is India sourcing with someone accountable for the rolls, not only for the quote.

You get:

• Supplier verification that includes the print technology on the floor. Chromojet or Colaris, head condition, color kitchen discipline, and whether the mill actually owns the line.
• Custom product sourcing from your artwork through strike-off, production-intent sample, and bulk. Logo mats, branded borders, suite rugs, and wall-to-wall packages are handled as one program, not as three chat threads.
• Quality control at multiple stages: pre-production sample, in-line checks during tufting and printing, dye lot and colorfastness, pile consistency, and third-party pre-shipment inspection.
• Private label manufacturing with your brand on the label, the edge binding, and the packing, without the mill learning your customer list.
• Wholesale supply at mid-range commercial pricing, negotiated at the mill, without a chain of intermediaries marking up a product they never inspected.
• Export logistics with commercial invoice, packing list, bill of lading, and certificate of origin prepared correctly, and HS codes that match the fiber and construction.

We handle your supply chain India from factory audits to final shipping. You work with one specialist, not a rotating set of factory contacts across time zones. Sample dispatch typically runs 5 to 10 days. Bulk production often sits in a 20 to 45 day window depending on construction and quantity. Those are planning numbers we track against the actual machine calendar, not slogans.

That is the opposite of a directory listing. You keep pricing confidential. The factory does not go around you. Competitive quotes do not leak to the next buyer shopping the same design.

Writing a hospitality print spec that a mill cannot dodge

Use language a production manager can execute.

1. Name the print system: Chromojet or Colaris (Zimmer), or equivalent only with written approval.
2. Name fiber, pile height, pile weight, and backing.
3. Require full dye penetration appropriate to that pile, verified by cross-section photos of production goods.
4. Require colorfastness to wet and dry rubbing and to light, with test reports.
5. Freeze the RIP file, color profile, and ink set after sample approval. No small improvements on bulk.
6. Define roll-to-roll shade tolerance and a reject rule.
7. State inspection rights: in-line and pre-shipment, with retained cuttings.
8. State packing, labeling, and document set for your destination (US, UK, UAE, or elsewhere).

If the mill will not accept that list, you do not have a hospitality supplier. You have a sample shop.

Chromojet or Colaris for your property mix

Choose Chromojet when:

• You are covering long corridors, ballrooms, airports, or cinema halls
• Pile is higher or structured
• Wear and chemical cleaning matter more than photographic detail
• Volume is large and design changes are infrequent

Choose Colaris when:

• You need fine artwork, logos, or short-run custom designs
• Pile is shorter
• You expect reprints, seasonal designs, or many SKUs
• Waste and changeover time are costing you more than jet coarseness

Use both in one brand program when:

• Public circulation is Chromojet wall-to-wall
• Suites, feature rugs, and promotion mats are Colaris
• Your sourcing partner keeps dye palettes coordinated so the lobby and the suite do not look like two different hotels

That split matches how the technologies are described as complementary, not as rivals, by textilegence.com and zimmer-austria.com.

Cost without the wrong kind of cheap

This is mid-range contract product, not a race to the lowest GSM. Under-specified print looks cheap in month six, which costs more than a correctly specified Chromojet corridor. Over-specified Colaris on a high-pile runner can also waste money if the detail never survives the pile geometry.

Netyex negotiates mill pricing and then spends the difference that used to sit in middleman markups on inspection and process control. You still buy at a commercial India cost. You do not buy an uninspected roll.

FAQ

Is Chromojet always better for hotels?No. It is usually better for high-traffic wall-to-wall with deeper pile. Guest-room rugs, logo mats, and detailed feature pieces often print better on Colaris. Audit the construction, not the brand name of the machine.

Can Colaris match Chromojet penetration?On short pile, yes, when pre-treatment, ink, and steaming are correct. On high, structured pile, Chromojet remains the more proven tool. Do not accept a verbal full penetration claim. Cut the yarn.

How many colors do I need?Chromojet lines often run 8 to 16 spot colors. Logo-mat machines may carry more so the mill is not constantly changing shades. Colaris mixes from 4, 6, or 8 bases. More bases can mean a wider color range. They do not replace a penetration test.

What should a US, UK, or UAE buyer put in the inspection plan?Pile height and weight versus the sealed sample, print registration, dye lot versus the standard, colorfastness, cross-section penetration photos, and a pre-shipment check before sealing. For multi-site hospitality, keep retained cuttings from each dye lot.

How do I source custom printed carpet from India without losing control?Use custom product sourcing with buyer-side representation. That means supplier verification, sample control, in-line quality control, and export logistics under one brief. Avoid placing bulk with a contact you found only on an unverified directory.

What documents do I need to import?A commercial invoice, packing list, bill of lading, and often a certificate of origin. Carpets classify under specific HS codes by material and construction. Misclassification creates duty and delay problems. This is part of export logistics, not an afterthought.

How long does it take?Plan 5 to 10 days for sample dispatch and roughly 20 to 45 days for bulk, depending on tufting, print queue, and finishing. Printed hospitality goods can sit longer if the Chromojet or Colaris calendar is full. Ask for the machine slot, not a round number.

Can I run private label manufacturing on these printers?Yes. Private label manufacturing is normal on both Chromojet and Colaris: your designs, your labels, your packing. Keep the mill from owning the customer relationship. That is a sourcing-structure problem, not a print-head problem.
