File preparation
Pre-print DTF checklist
Verifiable art, gang sheet, press and logistics list before spending film.

Art: file and dimensions
Confirm document is actual print size in cm or inches, not only “looks big” on screen. Check effective 300 DPI in critical areas (type, logos). Review file name: client, order, piece, PRINT version.
View on black and white backgrounds: no halos or unwanted soft transparency. If type exists, outlined or embedded per supplier policy. You exported PNG-24, not accidental JPG.
Define white note: full under all color, only under specific areas, or none (light garments only). Ambiguity here costs a meter. Attach client approval screenshot with date.
Compare visually to same client’s last order if they say “same as last time”. Same-name files in folders are a classic mistake.
Color, profile and digital proof
Color profile agreed with supplier (sRGB, CMYK, custom ICC). No double conversions from mobile app exports. If corporate, is there Pantone reference or approved physical sample?
Request RIP render or preview if the portal offers it; does not replace fabric but catches broken alpha. Check digital qty matches paid order.
For heavy black or neon designs, confirm expectations in writing. Note on checklist “client accepts variation on dark fabric”.
Keep local copy of sent PNG; do not rely only on supplier cloud if disputes arise.
Gang sheet: layout and quantities
Count pieces on sheet vs order: sizes, distinct designs, duplicates. Each file in correct position? Minimum spacing per supplier respected. Rotation only if cutting allows.
Peel order and orientation noted if shop requires. Rush client marked visually, not only email subject.
If you built the meter, did any PNG rescale on upload? Rescaling breaks hardened edges. Final sheet version is the one you paid for, not draft.
Reserve corner for edge test on dark fabric on new clients or new colors.
Equipment, press and environment
Press calibrated: temperature with external thermometer if unsure. Even pressure, clean pad. Press time per current film and powder batch (not last month unlogged).
Shop humidity and temperature affect powder and cure; note rainy days and tweaks. Supplier head maintenance can shift tone—ask for notice.
If you press: test on scrap of same fabric before batch. If outsourced: confirm they received files and sheet without auto-reject for size.
Clean scissors, gloves and surface for cutting; hand oil on white film stains before press.
Order logistics and communication
Deposit received and written order with sizes. Promised date feasible with current queue. Client knows pickup or ship and shipping paid.
Correct blank in stock: color, size, brand. For 50 pieces, physical count before print. Size tags visible after press.
Message client on delay before they ask. Template: new date + brief reason + option. Silence hurts trust more than honest delay.
Pack and deliver: bag, care note, invoice/receipt if needed. Photo of finished order for internal archive.
Last look before paying for the meter
Walk checklist aloud with another team member if possible; two eyes catch errors one normalizes. Mark each item on paper or app; do not trust memory when rushed.
If any item fails, stop sheet payment until fixed. One hour delay costs less than reprinting a full meter.
Archive signed checklist or screenshot with order for learning: what failed last claim.
Print or save this list at your station. Pre-print discipline is the cheapest quality move you can make.
Checklist plus resources in one place
Using the same checklist every batch turns good practice into habit. Within weeks you will see fewer reprints and calmer clients because results are predictable.
Pair this list with transparency, PNG format and pricing guides for a full system from sale to press.
When art and sheets come from an organized library, the checklist finishes faster: fewer doubts, fewer lost files.
At Limited Library you get a DTF design membership, tools like the meter builder and vectorizer, and Canva templates to sell before you print.
FAQ
How long does the full checklist take?
5–15 minutes on new orders; 2–5 if repeat client with validated file.
Fabric test every time?
Recommended on large orders, new colors or untested fabrics. On exact repeats you may skip with logged history.
What if supplier rejects my file?
Fix per their reason (alpha, size, profile), bump PRINT version and rerun checklist before resending.
Can I automate part of the checklist?
Yes: Photoshop actions, quote templates and meter builders cut manual errors. Client approval stays human.
