What resolution quality is required for good print quality?
Images need to have a resolution of between 300 and 350dpi. If artwork is generated at a lower resolution, then the quality of the final printed job will be affected. Artwork must be generated at a resolution of 350dpi from the outset, as it cannot be magically enhanced at a later stage. Please note that it is not possible to use images from the internet for litho printing, as they have been optimized for computer screens in order to keep the file size down.
