Almost every ruined print job dies from one of four file problems — and all four are preventable in about five minutes. Here is what each term actually means, in plain English, and what happens when it is missing.
Bleed: why your background must be bigger than your card
Paper is cut in stacks, and cutting has a hair of natural movement. Bleed is an extra 0.125" of your background extending past the trim line, so when the blade lands a fraction off, the color still runs to the edge. Without bleed, that fraction shows up as a white sliver along one side. If any color or image touches the edge of your design, it needs bleed behind it.
Safe area: keep the important stuff away from the blade
The same cutting variance works in reverse: anything within 0.125" of the trim line risks getting clipped. Keep logos, text and phone numbers inside the safe area. A border running exactly parallel to the edge is the classic trap — even a tiny shift makes it look lopsided. Either make borders thick or skip them.
CMYK: the color space printers actually use
Screens mix light (RGB); presses mix ink (CMYK). Some vivid screen colors — electric blues, neon greens — simply do not exist in ink, so an RGB file gets converted at print time and can shift noticeably. Convert to CMYK yourself before submitting and you will see roughly what the press sees, with no surprises.
Resolution: 300 DPI at final size
Small-format print needs 300 dots per inch at the printed size. A logo that looks sharp at web resolution turns soft on a business card. The test: view your file at 100% zoom at actual size — what you see is what prints. Enlarging a small image never adds detail; it just enlarges the blur.
Fonts: outline or embed
If we do not have your font installed, an un-embedded file substitutes another font and your layout reflows. Export a print-ready PDF (which embeds fonts) or convert type to outlines before sending.
The FlashyPrint safety net
Every order includes a free artwork check — a person reviews bleed, safe area, color mode, resolution and fonts before anything prints, and contacts you if something needs fixing. No file yet? Our design team builds print-ready artwork from scratch. Prefer to fix it yourself? Start your file at the product's stated size plus bleed, work in CMYK at 300 DPI, and you are ninety percent of the way there.
