First of all, we would like to stress that we are fans of vector graphics! Perfect vector graphics are the ultimate for us. The file resolution should be at least 300 dpi. Make sure that the contour or line thickness is at least 0.4 mm and the distances between colored areas should be at least 0.6 mm to avoid fusion when pressing.
Our printing area is 390mm by 520mm .
Possible file formats : "pdf", "png", "ai", "svg"
PDF vs PNG : We generally recommend using PDF as the preferred print file format. The edge quality remains high, especially with vector-based graphics. PNG tends to rasterize images and convert them to RGB when exporting, which is optimized for web display. The rasterization means that color gradients can appear at the edges, with only 2% color remaining at the end. The DTF printing software fills these incomplete pixels with white. Cut-out JPEG files can only be converted to PNG. For optimal print results, we recommend an image resolution of 300 dpi.
Colouring : Please avoid using special colours such as Pantone or HKS shades as this can lead to colour deviations. Colours in the RGB colour space are ideal for DTF printing, while the CMYK colour space is also possible, but with potential colour deviations. We recommend creating your print data in the RGB colour space to minimise colour deviations as much as possible.
Line thickness : It is important to ensure that individual lines have a line thickness of at least 0.5 mm. Otherwise, the adhesive may not be able to be applied properly in those places because there is not enough surface area available for the adhesive. In addition, incorrect color representations may occur. The line thickness only affects individual lines. The line thickness is not relevant within a motif.
Fonts : Basically, we can print any font. However, it should be noted that playful or eroded fonts can produce undesirable effects. This occurs when the recommended line width is not reached. Since we do not have every font in our font library, it is imperative to ensure that the fonts are converted to paths or curves.
Gradients : It is not advisable to use gradients that are translucent or have a lower coverage. The white background can lead to steps or incorrect representation of the gradient. Gradients from color to color with full coverage can be printed without any problem.
Gray tones : To correctly create gray tones in the DTF printing process, only black ink particles (K-Black) should be used. The colors cyan, magenta and yellow should not be used to create gray tones, as mixing them can cause an undesirable color cast and discoloration in the result. If gray tones are created with cyan, yellow and magenta, this can lead to a blue or green cast in the gray tone. This is because the DTF printing process is based on the subtractive color system and each of the colors cyan, yellow and magenta has a certain color intensity. By mixing these colors to create gray tones, the resulting color may not always have the desired gray shade.
Motif backgrounds : We print the data as you provide it to us. For motifs that are sent with a white background, this will be printed. It is white, but does not contain any color. Colored areas must not be overprinted, otherwise they will be printed in the print and this could lead to an undesirable print result.
You can also check each file yourself with Adobe Reader. Open your file and you can go to Edit -> Preferences -> Page Display -> Page Content and Information -> Show Transparency Grid
Now you can see where a white space is and how your design will be printed. This is just a quick way to check. However, if there are hidden layers in your PDF, for example, these will not be displayed. However, the DTF printing software recognizes the layers. Therefore, it is important to delete all unnecessary and hidden layers.
What else needs to be considered: The file length must not exceed 0.5 meters!
Have you cut out an image and want to use it? Please pay attention to the resolution! The more perfect it is, the better the edges will look. Remember to export your data with the correct PPI values. The files are also not scaled here. If your files are slightly too small, this will not be registered as an error, but will simply be printed as is. Please also avoid shadows! The glue will give them a white background! We do not need a cut contour (cutting line). Get rid of it! Please do not mirror the graphics. The printer mirrors automatically! All areas must not be set to overprint.
