Color Space defines how to treat colors and images on saving:
You can simulate the effect of Color Space on-screen by activating "View > PDF Proof Mode".
Resolution defines the resolution for images stored in a PDF-file. Note that images will never be enlarged but only scaled down if needed. This value is also used, if a layer having non-PDF-compliant properties has to be converted into an image on saving. Aside from various dpi values there is the setting Document. Using that the layer will be saved in the same quality it was created in the document. 72 dpi can be used as screen quality.
Transparency is still a problem in PDF. Since version 1.4 PDF files can contain smooth transparency, but until now most print shops prefer PDF files with version 1.3. But this version of PDF is quite restricted in displaying transparency, because it can only display 1-bit transparency (in contrast to 8-bit transparency of PhotoLine). Therefore you have the choice to remove the transparency from a document or to replace it by 1-bit. Both ways have disadvantages, but usually it is better to use Replace Background, this means removing the transparency completely. Of course it is best to avoid this problem at all by not using transparency, if the document should be saved as PDF.
With Bleed you can specify how far beyond the page boundaries PhotoLine creates the document content. This bleed width is usually specified by your print shop. If you activate Crop, PhotoLine will create an additional clipping path for the bleed width. Normally this is unnecessary.
In order to ensure a document looks the same on a different computer, fonts contained in a document can be embedded in a PDF-file. But there are two restrictions: PhotoLine can only export TrueType-fonts and this only, if it is permitted by the font. Some fonts forbid to be stored in document files. Note, that font embedding may increase the resulting file size enormously. Due to this Fonts offers several ways to treat fonts used in a document:
Image Compression controls, how to compress images. Which option to use largely depends on desired area of application. If you want to print the document or process it any further, you should use ZIP quick or ZIP best, if the document is used for viewing onscreen, one of the JPEG variants is suitable, because they lead to smaller files.
Text Compression controls, how to compress page description commands and black/white-images. There is no reason, why you shouldn’t always use ZIP best.
The command Layer/Display/Print Layer (see chapter 7.5.32) controls whether a layer is only shown onscreen or is printed, too. By turning on Export Only Printable Layers this setting is used for the PDF-export, too.
If a document, that should be saved as PDF, is a slideshow (see chapter 7.1.14), Start Slide Show In Full Screen Mode controls whether the resulting PDF opened with AdobeĀ® ReaderĀ® will be shown full screen.
