When it comes to printing, a great final product starts long before anything hits the press. One of the most common reasons projects get delayed, reprinted, or come out differently than expected is simple file setup mistakes.

The good news? Most of these issues are easy to avoid with a little preparation.

Here are some of the most common file prep mistakes we see and how to avoid them before your next print project.

Low Resolution Images

An image may look perfectly fine on a phone or computer screen, but that doesn’t mean it’s print-ready.

For high-quality printing, images should typically be at least 300 DPI at the final print size. Screens only display at a fraction of that resolution, which is why blurry or pixelated images often go unnoticed until production begins.

If you’re stretching a small image to fit a large banner, poster, or sign, quality loss becomes very noticeable.

When in doubt, send the original file instead of screenshots or compressed images.

Missing Bleeds

Bleed is the extra space added around the edges of a design so nothing important gets cut off during trimming.

Without bleed, you risk getting thin white edges around the final print piece. Standard bleed setup is usually 0.125 inches beyond the trim edge, but requirements can vary depending on the project.

If your artwork extends to the edge of the page, bleed matters.

RGB Instead of CMYK

One of the biggest surprises in print comes from color differences.

Digital screens use RGB color mode, while printers use CMYK. Some bright colors you see on-screen simply cannot be reproduced exactly in print.

Designing in CMYK from the beginning helps create more accurate expectations and smoother color matching during production.

Fonts That Aren’t Embedded

Nothing disrupts a layout faster than missing fonts.

If fonts aren’t embedded or outlined properly, they can substitute automatically when opened on another system. That can completely change spacing, formatting, and design alignment.

To avoid issues:

• Embed fonts in PDFs
• Outline fonts when necessary
• Package working files properly

Incorrect File Types

Not every file format is ideal for production.

While JPGs may work for small projects, print-ready PDFs are almost always preferred because they preserve layout, fonts, vectors, and color settings more reliably.

Sending editable source files alongside PDFs can also help if adjustments are needed during prepress.

Not Checking Final Dimensions

This happens more often than people realize, especially with large format graphics.

A design created at the wrong scale can delay production or affect image quality once resized. Always double-check final dimensions before exporting files.

This is especially important for:

• Trade show displays
• Window graphics
• Wall murals
• Construction signage
• Large banners

A Little Prep Goes a Long Way

Print production works best when files are set up correctly from the start. Good file prep helps reduce delays, avoid unnecessary reprints, and ensure the final product looks exactly how it should.

At Precision Images, we work with clients every day to make sure projects are production-ready before printing begins. Whether it’s a simple flyer or a large-scale installation, proper setup makes all the difference.
