    PDF is what we want. If all you have is a native layout file, send it and say so — prepress will tell you what it still needs. This form takes up to 20 MB in one go — anything bigger goes faster as a transfer link, so put the link in the box above or email it to print@omegalith.com.

    How to build a file that prints

    Most jobs that stall in prepress stall for one of seven reasons. None of them are hard to avoid, and all of them are cheaper to fix in your file than on a plate.

    1. Send a press-ready PDF

    Export to PDF/X‑1a or PDF/X‑4 if your software offers it. Those presets exist precisely to stop the things that go wrong: they force fonts to embed, flatten or preserve transparency predictably, and carry the trim and bleed boxes with the file. A PDF is also the only format that looks the same on our screen as it did on yours.

    2. Embed or outline the fonts

    A font that is not embedded gets substituted, and substituted type re-flows — lines break in new places and a two-line heading becomes three. Embedding keeps the type you set. Outlining converts it to artwork, which is safe but no longer editable, so outline last and keep your working file.

    3. Images at 300 ppi at final size

    The resolution that matters is the resolution at the size the image is printed, not the number in the file. A 300 ppi photo scaled to 200% is a 150 ppi photo. Web images are usually 72 ppi and will not hold up on paper, however good they look on a screen. Line art and logos are better supplied as vector, where resolution stops mattering at all.

    4. CMYK, not RGB

    A screen makes color with light and a press makes it with four inks — cyan, magenta, yellow and black. Convert to CMYK yourself and you decide what happens to the bright blues and greens a press cannot reach. Leave it in RGB and the conversion happens without you. If a specific brand color has to be exact, ask about a spot ink instead: it is mixed to a number rather than built from four screens.

    5. 1/8 inch of bleed where art runs off the edge

    Bleed is artwork extended past the trim line — 0.125 in on every edge the ink runs off. Sheets are trimmed in stacks and the knife moves a hair through the lift, so without bleed a white sliver shows on some copies and not others. Extending the background is the whole fix.

    6. Keep live matter clear of the trim

    The same knife movement works inwards. Keep type, logos, page numbers and anything else that must not be clipped at least 1/8 inch inside the trim — more on a thick saddle-stitched booklet, where the inner pages creep outwards as the spine gets fatter and get trimmed harder.

    7. Name the file so a human can read it

    acme-spring-catalog-v3-2026-04-12.pdf tells us what it is and which version it is. final_FINAL2.pdf tells us nothing, and two of them in one folder is how the wrong version gets printed. Supply multi-page work as single pages in reading order rather than as reader spreads — imposition is our job, and pages pre-paired into spreads have to be taken apart again.

    Then look at the proof. Proofs come back as an emailed PDF or as a hard copy. Read the spelling, the phone numbers, the web addresses, the page order and the folds. A PDF on an uncalibrated monitor will not tell you the truth about color — ask for a hard copy when the color is the thing that matters.
