Which Is the Best and What Are the Differences?
Jpeg, psd, png or pdf? Generally we define two groups of file formats: Open formats and Postscript formats, however, for professional printing only Postscript files are suitable to ensure a clearly defined result. Examples for Postscript formats are jpeg, tiff or pdf.
Open formats are any file which can be opened by a particular software in order to make adjustments (for example .ai for Adobe Illustrator, .psd for Photoshop, .doc for a Word document). Usually these files include only a guideline of the file appearance, for example the name of the different fonts used for the layout and a link to the font file, but not the entire resource file. Thus, such files may change their appearance depending on the circumstances on the device on which they are opened. To stay with the example above, if the link to the font file is leading to a different font with same name, typographic changes are very likely.
On the other side, in Postscript file formats, all important information is embedded. Meaning, they can be viewed on any device and in any environment without changing their appearance. However, it is not possible to edit them in an easy way.
Open Formats From Vector Softwares
If data from vector programs such as Illustrator or CorelDraw are sent to us, it is extremely important that all fonts are "converted to outlines". Otherwise we will not have the required fonts and this may lead to delays.
The PDF Export Settings
For PDF files, please ensure that all fonts are embedded and all images are converted to the CMYK color mode. Please do not use trim marks but rather ensure your document is set up correctly with a 0.1” bleed on all four edges and that the document settings are included in the exported pdf (checkbox to enable in the export settings).
