Choosing the Base Fabric for Digital and Rotary Printing

What must a print base do that a dyeing base does not?

Dyeing asks the whole cloth to absorb colour evenly; printing asks the surface to hold a design in place. That adds three demands a dyeing base never faces. First, surface uniformity: ink sits where it lands, so every slub, nep and density variation prints. Second, controlled surface absorbency: too absorbent and lines bleed, too repellent and colour sits up and rubs off — which is why print bases carry route-specific pretreatment rather than generic preparation. Third, dimensional stability through the machine: a cloth that skews or stretches under tension prints a distorted repeat that no operator can correct afterwards.

What do digital and rotary printing each demand of the base?

The minimums are decision inputs, not sales lines: at 100m per colour per design, a multi-design digital capsule is reachable at a scale rotary's screen engraving can never serve — and at genuine volume the economics reverse. The base follows the same split: what digital demands of the face, rotary often forgives.

Why does construction density decide print definition?

Ink lands on yarns and the gaps between them. On an open, coarse construction a fine line falls partly into the gaps, spreads along the yarns and breaks at every crossing — the edge that looks crisp on screen prints ragged. On a dense, even face — a high ends-and-picks shirting construction such as a poplin — the same line lands on a nearly continuous surface and holds its edge. The rule of thumb that follows: the finer the artwork detail, the denser and more even the face must be, and no printer setting compensates for a base that is too open for the design.

Buyers assume a blurry print is a printing fault. Often the base was wrong — and reprinting the same artwork on the same base reproduces the same blur. The check is procedural, not optical: match the artwork's finest line to the construction class before purchase, then prove it with a strike-off on the actual base — never on a substitute cloth.

For what a construction figure does and does not fix, see how to read fabric construction.

Is PFD one product?

No — and treating it as one is how the wrong base gets bought. PFD (Prepared for Dyeing/Printing) means prepared to the requirement of one named route: a base pretreated for reactive printing is not automatically suitable for pigment or disperse work, and none of them rescues an unsuitable fibre — sublimation requires a suitable polyester base regardless of pretreatment. The full RFD-vs-PFD distinction, and the sequencing rule that PFD cannot be ordered before the route is fixed, is covered in the processing-states comparison — this page only needs its consequence: "PFD" on a quotation is a category, not a specification, until the route, whiteness and absorbency are named.

The states themselves are compared in greige vs RFD vs PFD — including why the route must be fixed before the base is bought.

What does the print route imply for order size?

The base decision and the quantity decision are the same decision seen twice. Digital's 100m per colour per design minimum means a launch can carry several designs on one prepared base quality — the base is bought once and the designs vary. Rotary's 3,000m minimum means the design set is small and the base volume is large, so a base fault multiplies across the whole run: the cheaper place to catch it is the strike-off, not the bulk.

How these minimums combine with dyeing minimums across a whole programme is set out on low-MOQ fabric sourcing from Pakistan.

How do you specify a print base so the printer does not guess?

• 1. Name the route and ink system — digital or rotary; reactive, pigment or disperse; sublimation declared explicitly (it fixes the fibre).
• 2. State the artwork demand — finest line width, photographic gradients, coverage — so the construction class can be matched to it.
• 3. Ask the printing unit to state the base requirement in writing — pretreatment, whiteness, absorbency, width and heat-set state where relevant — before the base is bought.
• 4. Approve a strike-off on the actual base construction, and write that construction into the approval.
• 5. Confirm shrinkage and handfeel after fixation and any wash-off the route requires — most print routes are also wet processes, and the finished figures are measured after them.

Five lines, and every one of them moves a failure from bulk — where it is expensive — to paper, where it is free.
