Rotary screen printing pushes colour through engraved cylindrical screens, one per colour, as the fabric passes beneath them, while digital printing sprays the design directly from a file with no screens at all. Rotary needs a set of screens engraved for every design, which makes it expensive to set up and gives it a high minimum order quantity (MOQ), but it runs fast and the cost per metre falls sharply at volume. Digital has almost no setup, handles any number of colours and suits short runs, but it is slower and costs more per metre. Most buyers in Surat end up using both, with the split decided by quantity per design and the type of artwork.
Side by side
- Setup: rotary needs one engraved screen per colour, digital needs only a print file.
- MOQ: rotary is usually in the thousands of metres per design, digital is often a few hundred metres or less.
- Speed: rotary runs many metres a minute, digital runs at a fraction of that.
- Cost per metre: rotary is lower at volume, digital is higher but roughly flat regardless of quantity.
- Colours: rotary is limited by the number of screens the machine holds, typically up to around a dozen, digital is unlimited.
- Repeat size: rotary is fixed by the screen circumference, digital can be any length.
- Artwork: rotary suits flat colours and clean geometric or floral repeats, digital suits gradients, photographs and fine detail.
- Colour depth: rotary lays down more paste, which gives stronger solids and better penetration on heavier fabrics.
When rotary is the right choice
Rotary makes sense when a single design will run in volume, when the artwork uses a limited number of flat colours and when deep, well-penetrated shades are needed. It is also better for heavier fabrics and for designs that will be reordered over several seasons, because the screens can be stored and reused. Registration drift between colours is the main quality risk, so the first production metres should be checked against the approved strike-off.
When digital is the right choice
Digital is the choice for sampling, for ranges with many designs in small quantities, for photographic or painterly artwork and for any job where speed to market matters more than cost per metre. It also avoids the waste of screens that are used once. The main quality risks are colour fastness, which depends on fixing and washing rather than the printer, and colour matching to a screen proof. For polyester, sublimation transfer is a form of digital printing that lowers both cost and MOQ further.
How we help
We visit the process houses offering both methods, check their equipment and processes and tell you plainly which method suits each design in your range. We audit the units, send sealed samples to an NABL-accredited lab, inspect rolls before loading and supervise loading. Weekly updates keep you informed, and we hold one approved printer plus one backup. A free 20-minute sourcing review is a practical way to decide the rotary and digital split for a new season.
