How to prepare a file for printing?

Many people wonder what it takes to prepare the correct graphics for printing. Few people know what elements make up the quality of the file so that when sent to the printing house it does not raise any objections.

File format

Because of the graphics software used by the graphic designer and our printing house, it will be crucial to save the file in the correct format. This will avoid unnecessary errors. The formats we accept are .cdr, .eps, .ai, .pdf, .png, .jpg. We do not work on .svg files, as they do not work properly with our graphics programs.


Graphics for print work best when prepared in vector and the lettering is converted to curves. The most common format for saving vector graphics is .pdf, but attached .cdr, .eps and .ai files are also welcome. Working in graphics programs such as Corel or Adobe Illustrator allows you to save vector graphics, which is important when the project is to be printed in different sizes, since modifying the size of the graphic does not adversely affect its quality. Saving in vectors will work well for such printing techniques as flex and flock, screen printing or embroidery, as well as embossing, pad printing and engraving for advertising gadgets.


These forms of saving are also accepted. However, be sure to save the graphics as a large image, with a resolution of 300 ppi, otherwise the so-called “pixelosis”, or blurriness, may appear, which will be visible in printing. Graphics saved to .jpg will work best for sublimation and sublimation printing, while .png (preferably with a transparent background) will be suitable for DTF digital printing. Graphics saved to .tiff are also suitable for printing, but their weight is usually very high, so we advise you to avoid this form of saving 馃槈

CMYK or RGB, or maybe PANTONE?

Printing colors depend on the printing technique you want to use. For sublimation and sublimation, CMYK colors should be preset. However, for digital printing, in the case of our BROTHER GTX PRO printer, colors set in RGB come out best (even though the print is CMYK) – we know it’s messed up, but that’s just the way it is 馃槈 Whereas for screen printing and pad printing, colors should be specified in Pantone Solid Coated, since the inks are mixed according to special proportions given in the Pantone template. We are left with two more techniques for printing on garments, namely flex and flock foils. In the case of thermal transfer, it doesn’t matter what colors we give to the graphics, because the aforementioned films already have top-down colors imposed by the manufacturer, and we only cut them on the plotter and press them into the garment.

Resolution of 300 ppi what does it mean?

This means that your graphic will be printed in very high resolution, thus avoiding “pixelosis” and any blurriness. The larger the size / resolution of the graphic, the better the print. However, let’s not overdo it when saving the graphics you created 馃槈 300 ppi is enough.
