HOW TO PREPARE A FILE FOR PRINTING Whiterip works flawlessly with files created by PhotoShop and saved as PSD files. Suggested format: PSD, TIFF otherwise Resolution: > 180 dpi Suggested Resolution: 360 dpi Mode: RGB
Open the image in PhotoShop, then convert it to RGB.
HIGHER THE RESOLUTION TO AT LEAST 180 DPI Select Image ďƒ Image size ďƒ Resolution, then click ok. Note that the resolution of the images should already be higher than 180 dpi: using this method to get a higher resolution does not improve the quality of the image. If you want to know which is the best resolution for an image of a certain size (in order not to have the pixel-effect), you should select the resample option and write 180 inside the resolution field.
