I am a beginner in everything but especially GIMP. I used Inskcape to create a cover for my coloring book. It has multiple layers and transparencies. I know I have to flatten the transparencies. So to do this, I opened the svg cover I created in GIMP but it is just showing one layer in the layers panel. How do I upload my svg file in gimp and flatten the entire image to make sure when it prints I don't have trouble? I will need very beginner instructions with this very detailed (as detailed for each step as you possibly can since I don't know much about GIMP).
P.S. I would just flatten in Inkcape but I hear putting everything in one layer in inkscape doesn't really correlate to flattening all transparencies (something to do with alpha might still be there).
Billy - I just saw you asked what the requirements are. The following are the requirements to upload my Paperback cover to Kindle Direct Publishing. I made a cover in Inkscape but don't know how to flatten the transparencies. I'll eventually probably be asking how to embed the fonts but for now I don't know how to flatten all transparencies. :)
*Save as a PDF. Your cover must be a single PDF that includes the back cover, spine, and front cover as one image.
*Flatten all transparencies. These can cause the file to print with missing or distorted content. Consult your software's documentation to learn how.
*Embed your fonts. Consult your software's documentation to learn how.
*Remove crop marks, color bars, template text. Crop marks are lines showing where pages should be trimmed. Color bars are strips with a series of patches used to ensure color balance during printing. Also, remove any template text, PDF creation guides, or software references.
