How to prepare a file for printing?
Proper file preparation is the key to achieving excellent print quality. Our free tool lets you quickly check whether your file meets printing requirements, without uploading it to a server.
Pixels, not DPI — what really determines quality
DPI (dots per inch) is simply the ratio of pixel count to physical print size. The DPI value stored in file metadata (e.g. 72 or 300) does not affect image quality — it can be changed freely without modifying the image itself. Print quality is determined solely by the number of pixels relative to the intended size. For an A4 print (210 × 297 mm) you need approximately 2480 × 3508 pixels to achieve 300 dots per inch sharpness. The larger the print you plan, the more pixels you need.
File formats
The best formats for printing are TIFF and PNG (lossless) and high-quality JPEG (above 80%). SVG files are excellent for vector graphics such as logos. Avoid low-quality compression formats that can cause artifacts in print.
CMYK vs RGB color space
Monitors display colors in RGB (Red, Green, Blue), while printers use CMYK (Cyan, Magenta, Yellow, Key/Black). Converting from RGB to CMYK can cause color shifts, especially with intense shades of blue and green. We recommend preparing files directly in CMYK or using our CMYK simulation tool.
Transparency and layers
Files with transparency (alpha channel) can cause problems in printing. Before sending a file to the printer, it is recommended to flatten layers and remove transparency, replacing it with a white background, unless the transparency effect is intentional.
