Print-ready checklist

Updated 2026-10-12

The Core Takeaway

A print-ready file is not simply a high-resolution image; it is a document structured to survive the physical process of cutting, inking, and finishing. If you ignore the specific technical requirements of pre-press, you risk losing critical information to the trim line or receiving colors that do not match your screen. This checklist ensures your artwork is mechanically and optically compatible with standard offset or digital print workflows.

Dimensions and Bleed

The most common error in pre-press is insufficient bleed. Bleed is the area of artwork that extends beyond the final trim size to ensure no unprinted white slivers appear at the edges after cutting. For standard business cards, the trim size varies by region, but the bleed requirement is typically 1.5 mm to 2 mm on all sides.

When preparing your file, you must set the document canvas to the trim size plus the bleed on all four sides. For example, if your final card size is 85 × 55 mm and you use a 2 mm bleed, your canvas should be 89 × 59 mm. Always keep live artwork, such as backgrounds, bleeding to the edge of this expanded canvas.

Safe Area and Typography

While bleed handles the edges, the safe area protects the content. Standard pre-press guidelines recommend keeping all critical text, logos, and icons at least 3 mm inside the trim line. This buffer accounts for minor misalignments during the cutting process. If a logo sits too close to the edge, even a slight shift in the die-cut can clip a letter or a design element.

Color Management

Screens display light using the additive RGB model, while print uses subtractive CMYK inks. You must convert your file to CMYK before submission. Relying on a generic RGB-to-CMYK conversion can result in dull or shifted hues. Ideally, you should work with the specific ICC profile provided by your printer, which describes how their presses reproduce color. If you use spot colors, such as Pantone (PMS), ensure the file contains the specific ink names rather than CMYK approximations.

Resolution and Fonts

Raster images, such as photographs, must be embedded at a minimum of 300 PPI (pixels per inch) at 100% scale. Lower resolutions will appear pixelated in print. Vector elements, such as logos drawn in paths, are resolution-independent and remain sharp at any size. Before exporting, you must embed all fonts or outline them. If a font is missing on the printer’s system, the software may substitute it with a default typeface, altering the design’s integrity.

Final File Format

PDF/X is the industry standard for print-ready files. It ensures that all fonts, images, and color profiles are embedded and consistent across different operating systems. Avoid submitting editable source files (like AI or PSD) unless explicitly requested, as they can be unstable when opened on different software versions.

FAQ

Why does my file look blurry in the preview? This usually indicates that the image resolution is below 300 PPI or that the preview is being viewed at a zoom level that does not reflect print scale. Check the image properties in your design software to confirm the pixel dimensions match the physical size at 300 DPI.

Can I use RGB colors if I ask the printer to convert them? It is not recommended. While printers can convert RGB to CMYK, the conversion is often generic and may produce muddy results. You should always convert to CMYK yourself using the printer’s specific ICC profile to ensure accurate color reproduction.

What is the difference between a spot color and a process color? Process colors use a combination of Cyan, Magenta, Yellow, and Black (CMYK) inks to create a wide range of hues. Spot colors, such as Pantone, use a single, pre-mixed ink to achieve a specific, consistent shade that may not be reproducible with CMYK inks.
