File Preparation Determines Print Quality
Printing problems rarely come from equipment. They come from files that were not prepared correctly. In large and wide format printing, mistakes in file setup result in delays, reprints, colour issues, and wasted production time. Preparing print ready files correctly is one of the simplest ways to protect budgets and ensure consistent results.
The Most Common File Errors in Large Format Printing
Many projects arrive with hidden issues that do not show until production begins. The most common mistakes include wrong document size, low resolution images, missing bleed, incorrect colour space, fonts not embedded, transparent elements not flattened, and files exported incorrectly. These issues often cause rework, production delays, and unexpected costs.
File Size and Scaling
Always build files at final size whenever possible. If a file is too large to work natively, scale proportionally and note the output size clearly. Avoid resizing raster artwork at the print stage as this leads to pixelation and quality loss.
Resolution for Large Format
Resolution standards differ depending on viewing distance. Files intended for close viewing should be prepared at 300 DPI at the final size. Files viewed from a distance, such as banners or large wall graphics, may be acceptable at a lower resolution if designed correctly. Low-resolution files become visible quickly when printed large and create poor visual results. Best practice is to confirm the final resolution required for each printing method.
Colour Mode and Profiles
Use CMYK colour mode when preparing files for print. RGB colours may display well on screen, but often shift when printed. Using a proper colour profile ensures better accuracy and predictable output. Avoid relying on screen appearance alone.
File Formats That Perform Best
Preferred formats include PDF, TIFF, AI, and EPS depending on design software. PDF export settings should preserve quality, embed fonts, and flatten transparencies properly. Uncompressed files maintain better output quality than low quality exports. Include all the working packaged files whenever possible, along with the final pdf, in case any last minute adjustments are needed.
Fonts and Text
Always embed fonts or convert text to outlines before exporting. Missing fonts can cause reflow, spacing issues, or substitutions that affect layout. Nothing changes faster than missing typefaces during production.
Bleed and Margin Setup
Artwork that trims to the edge must include bleed. Without bleed, white edges can appear after cutting. Important text and logos should be positioned inside safe zones to avoid trimming issues. Bleed is not optional in professional printing. Standard bleed is 0.25″.
Proofing Before Sending Files
Always review files at full scale where possible. Zoom in and ensure that images don’t look choppy. Check edges. Verify spelling. Confirm colour intent. One missed detail can multiply across hundreds of prints. Files should never be assumed correct without inspection.
How AIIM Avoids File Related Failures
AIIM uses structured file review processes to catch errors before production begins. We confirm size, resolution, colour settings, and file integrity before printing. Our goal is to protect customers from preventable problems.
Good Files Save Time and Money
Each error prevented avoids wasted materials, labour, and rescheduling. High quality file preparation reduces downtime and delivers predictable results. Professional output begins before a file ever touches a printer.
