DTF Printing Guides

What direct-to-film actually is, how the process works step by step, what it prints well on, and what it costs in Canada.

Exact temperatures, times and pressures by fabric, why the second press is not optional, and the four mistakes behind most failed prints.

Why PNG is the safe default, when a PDF is genuinely better, and the reason a JPG prints a white box on a black shirt.

Resolution, transparency, edges, colour mode and sizing, with the pixel maths and a pre-flight checklist you can run in a minute.

305–315°F on cotton, 270–285°F on synthetics — and why your press dial is probably lying to you by 15 to 20 degrees.

10–15 seconds on cotton, 8–10 on synthetics, plus the pre-press and the second press. Why longer is not better.

40–60 psi, how to check it without a gauge, and why under-pressure is the number one cause of edges lifting in the wash.

Ours is cold peel — wait 20–30 seconds until the film is cool. Here is what happens if you do not, and how to tell the two apart.

Silicone sheet, parchment or Teflon for the second press — what each does to the finish, and the four things never to use.

Drop to 270–285°F for 8–10 seconds, and what to do about dye migration on light prints over dark performance fabric.

Wait 24 hours, wash inside out on cold, tumble low, never iron the print. Plus a care card you can copy into your packaging.

Longer than most people expect and shorter than most suppliers claim. What actually determines the lifespan of a print.

Edges lifting, ink pulling away with the film, cloudy patches, scorch marks and dye migration — the cause and the fix for each.

305–315°F for 10–15 seconds. Cotton is the most forgiving surface there is — here is how to get it right first time and what still goes wrong.

Curved surfaces need a cap press and a smaller design. Sizing, placement, seam problems and why a flat platen will not work.

Thick fabric changes your pressure, not just your time. 12–15 seconds, a pressure re-check, and how to avoid the pouch pocket seam.

Why a white print on a red polyester shirt turns pink three days later, and the four levers that actually reduce it.

Technically yes, practically no. What an iron cannot do that a press can, and what happens to the print a month later.

Clamshell or swing-away, platen size, even pressure and the specs that actually matter. We do sell presses now, so read it with that in mind — the advice has not changed.

Send RGB. Here is why converting to CMYK yourself usually makes things worse, and which screen colours will shift no matter what.

What the white layer does, why it is generated automatically, and why building one into your file yourself will ruin the print.

When a logo needs rebuilding rather than upscaling, how to tell the difference, and what auto-trace tools get wrong.

Every standard placement with real measurements — left chest, full front, back, sleeve, youth and plus sizes. Bookmark it.

Packing designs onto one sheet to cut wasted film. Spacing, grouping by height, and the mistakes that cost more than they save.

Total cost of ownership including ink, film, powder, curing, ventilation and the maintenance nobody mentions — against just buying transfers.

A costing method that includes your labour, plus realistic margins for fundraisers, retail and wholesale.

What you actually need to begin, what it costs, and the order to buy things in. Written for someone starting from nothing.

Eleven questions worth asking before you commit, including the three most suppliers would rather you did not.

What every method actually costs per shirt at 10, 50 and 250 pieces — DTF, screen printing, DTG, vinyl and embroidery — with the maths shown.

Production time and transit time are two different numbers, and most "24-hour turnaround" claims only cover one of them. Here is the honest arithmetic, city by city.

Trimming transfers by hand costs more time than most people account for. What $0.25 per copy actually buys back, and when to skip it.

Software catches resolution. It does not catch halo edges, hairlines that will break up, or a design sized wrong for the garment. Here is what a human review catches.

The lowest rate per square inch is rarely the lowest cost per usable transfer. Minimums, wasted film, customs and reprints are where the difference hides.

What to look at on the transfer before you press it, what to check after, and the only test that actually settles it.

Work backwards from the date. What can be compressed, what cannot, and the one strategy that removes shipping from your critical path entirely.

A flat $9.99 anywhere in Canada, free over $275 before tax, and one label per customer per day. Plus the two cases where that flat rate does not apply.

Order at 9 AM, remember something at 2 PM, and the second order ships free with the first. The bundling rule most customers never find out about.

What a wholesale rate is, what actually moves it, why volume tiers are usually theatre, and the questions that tell you whether a rate is real.

For screen and embroidery shops adding DTF without buying equipment — quoting it, scheduling it, and the margin maths that decides whether it works.

Buying transfers and reselling them without owning a press. What the margins really look like, what blind shipping changes, and where it stops working.

Same-day printing sounds like a corner being cut. Here is which steps can be compressed without cost, and the two that genuinely cannot be rushed.

White ink density, powder consistency, cure control and film choice. The four variables that separate a good transfer from a cheap one — and how to check each.

White ink is the one that decides everything — cost, maintenance and print quality. How much you actually use, how to store it, and what to check before buying.

Roll or sheet, cold peel or hot peel, and the thickness and coating differences that show up in the print. What to buy for the way you actually work.

Fine, medium or coarse, how much a sheet actually consumes, why humidity ruins a bag, and how powder choice shows up in wash durability.

An honest comparison including where screen printing genuinely wins, and the order size where the crossover happens.

Fabric compatibility is the decisive difference. Plus colour on darks, cost per unit, hand feel and which suits small runs.

Sublimation cannot print on cotton or on dark garments. That one fact decides most of these comparisons before anything else does.

Every colour in HTV is another layer to cut, weed and align. Where vinyl still wins, and the point at which it stops making sense.

One question settles it — is the thing you are decorating made of fabric? Everything else is detail.

The rate per square inch is identical. What changes is how much empty film you pay for — with worked examples showing the crossover.
