Digital textile printing applies a pattern directly onto fabric with inkjet, without physical screens, which is what makes short runs and fast turnaround possible. This article looks at what digital printing actually is and how it differs from screen printing, the main technology families (direct to fabric, sublimation, pigment, and discharge), and the complete production process from design through file preparation, proofing, and final production. It covers the technical requirements that matter before submitting a file, resolution, color mode, and file format, and how Pointcarre's Natural Blend Color feature predicts the final result before printing to reduce wasted samples, before placing digital printing alongside rotary and screen printing as a production choice rather than a design tool choice.

Digital printing has fundamentally changed how textile patterns move from design to production. No more waiting on screen preparation to test an idea, no more discouraging minimum order quantities for a small run. But behind the apparent simplicity of inkjet on fabric lies a precise technical process, where a single mismanaged step can ruin an entire production run. This article breaks down that process stage by stage, for textile designers, style offices and manufacturers who want to understand what actually happens between the screen and the finished roll of fabric.

What is digital textile printing

Digital textile printing refers to the set of technologies that apply a pattern directly onto a textile substrate using computer driven inkjet printheads, without producing physical screens. That is the fundamental difference from traditional screen printing. Screen printing must break a multicolor visual down into separate color layers, each corresponding to a screen and an ink pass on the press. Digital printing reads the file directly and reproduces the image in a single pass, regardless of how many colors or gradients the pattern contains.

That difference has real consequences across the whole production chain. Minimum order quantities are much lower in digital printing, often between 1 and 50 meters, compared to 50 meters and up for screen printing. Setup costs are reduced since there are no screens to prepare, and turnaround times are shorter. In exchange, cost per meter is generally higher than screen printing at large volumes, which is why the two technologies continue to coexist depending on the project.

The main technology families

Not all digital textile printing is equal. The right technology depends directly on the fiber of the substrate and the finish you are after.

Direct to fabric printing applies dye straight onto pretreated fabric, using reactive inks for cotton or acid inks for silk and wool. It requires steaming after printing (roughly 20 to 30 minutes at 102 degrees Celsius for reactive dyes) to fix the colors permanently, followed by a wash that removes excess dye and pretreatment residue. This method delivers the best washfastness on natural fibers.

Sublimation works differently. The pattern is first printed onto transfer paper with sublimation inks, then heat pressed (180 to 210 degrees Celsius, 45 to 60 seconds) against polyester fabric. The dye moves directly from solid to gas and bonds with the synthetic fibers. No post treatment is needed, color saturation is excellent and water consumption is essentially zero. The limitation is strict though. This technique only works on polyester or polymer coated surfaces.

Pigment printing uses pigment inks compatible with virtually any fabric type, with medium to high detail and fast production. Discharge printing combines a discharge agent with a dye, particularly useful on dark cotton or blends, though it runs slower than the other methods.

The complete process, from design to finished fabric

A digital textile printing run always follows the same arc, regardless of which technology is chosen.

The first step is design. This is where creativity happens, but also where technical feasibility gets decided: proportions, scale, and getting the repeat right so the pattern flows without a visible break across the width of the fabric. This is a moment where a tool that speeds up creation without sacrificing control makes a real difference. Pointcarre's Design Maker module generates patterns at any size, in repeat, using a reference image to keep the output true to the designer's own style, which considerably shortens the distance between an idea and a production ready file.

Next comes file preparation: resolution, color mode, dimensions and color profile all need to match the printer's requirements before submission. This is a stage where mistakes are common and expensive, and where the repeat has to be flawless, since a repeat flaw that is invisible on screen becomes very visible once the fabric is unrolled across several meters. Pointcarre's Repeat Maker automates the seamless repeat of an imported image, a feature not every textile software vendor offers.

The third step is proofing: a test sample, known as a strike off, is produced before the full run launches. This is when color accuracy and actual scale get checked. If discrepancies show up, you move into a revision phase, adjusting color, scale or repeat. This is exactly where clean color channel work pays off. The tighter the color separation upstream, the fewer proofing rounds are needed. Pointcarre's Print module handles color separation up to 56 channels, with direct Photoshop channel import and export, avoiding the need to rebuild the same work across two different pieces of software.

Once colors are approved, production can start: the final file is sent to the printer, who produces the yardage on the specified fabric. Post treatment follows (steaming, washing, heat setting depending on ink type), then quality control (color consistency, absence of defects), and finally finishing (cutting, hemming, additional treatments such as softening or water repellent coating).

The technical requirements worth knowing before submitting a file

A poorly prepared file is the single most common cause of production rework. A few technical rules avoid the majority of problems.

On resolution, digital textile printing generally calls for 150 to 300 DPI, with 300 DPI recommended for fine detail. Sublimation tolerates a bit less (150 to 200 DPI) due to natural dye diffusion, while large format wall decoration can get away with 100 to 150 DPI depending on the intended viewing distance. To put the file weight in perspective: a one square meter pattern at 300 DPI works out to roughly 11,800 pixels per side, close to 420 MB uncompressed in RGB. That is why digital textile work demands processing power and file management well beyond a typical graphics workflow.

On color, RGB is used during the design phase and for most digital printing, since most printers handle the conversion internally. CMYK remains required for certain industrial printers. An 8 bit per channel depth is the minimum, with 16 bit preferred for high end work to preserve tonal gradients without visible banding.

On file formats, TIFF (uncompressed or LZW compressed) remains the industry standard for production because it preserves channels and color profiles. PSD retains full editability (layers, masks). PDF suits vector designs and client presentations well. PNG, on the other hand, should stay limited to web proofing. Its compression artifacts make it unsuitable for final production.

This is exactly where Adobe Photoshop file compatibility matters in a professional setting. Being able to import and export Photoshop channels directly inside a textile CAD software, rather than manually rebuilding every separation, saves considerable time on complex patterns. This is also where Pointcarre exports to the leading RIP systems and digital printers on the market, including Epson and Mimaki, closing the loop all the way to the production machine.

Predicting the result before you print

One of the most expensive challenges in textile printing is the gap between what you see on screen and what actually comes off the machine. A color mix that looks balanced on a monitor can turn out dull or unbalanced once printed, especially when several close shades overlap optically. Narrowing that gap upstream, before the first strike off, cuts down on the number of physical samples needed and therefore on wasted fabric and ink.

That is the role of Pointcarre's Natural Blend Color feature, which simulates ink mixing before production. By predicting the actual output of a file, it reduces the number of rolls or cylinders needed upfront, with optimized ink use and fewer physical samples to produce. It is both an economic and an environmental advantage, particularly relevant in a textile industry increasingly focused on its footprint.

Another point that is often underestimated: the depth of the color library available upstream of separation work. A designer limited to a thin or paywalled palette runs a higher risk of color mismatch in production. Pointcarre includes the Pantone Textile Library, the Archroma Color Atlas (5,760 colors) and ColorCSI at no extra cost, where these libraries are typically charged separately by other vendors.

Screen printing or digital printing: a production choice, not a tooling choice

It is worth remembering that channel based color separation, as described above, still matters even when final production runs through screen printing rather than pure digital output. Screen printing requires breaking every visual down into monochrome layers, each corresponding to a physical screen, with its own challenges around registration, halftone and screen angles to avoid moire effects. Digital printing sidesteps that constraint entirely since the file is read directly, with no intermediate screen.

The choice between the two is therefore not a design tool choice, it is a production choice, driven by volume, turnaround and substrate. A single piece of textile CAD software, properly equipped for channel management and repeat handling, should be able to support a designer regardless of which technology is used downstream. That is exactly the logic behind Pointcarre's Print module, built to cover digital, rotary and screen printing within a single working environment.

In summary

Digital textile printing has opened up short runs, fast turnaround and personalization, but it remains a demanding technical process. The right resolution, a consistent color mode, a flawless repeat and an accurate prediction of the final color output are what stand between a clean production run and costly rework. For more than 40 years, Pointcarre has supported style offices and textile manufacturers across this entire chain, from the first pattern sketched to the export toward the market's leading digital printers, all within a single application, native on both Mac and PC, with no reliance on third party plug-ins.
