PDF Transparency Problems with LuLu Publishing


Recommended Posts

Hello:  Each time I've uploaded my book's PDF to lulu.com, they return an error message saying, "Transparency: We detected an element that may be transparent within your file. We strongly recommend flattening or removing any transparencies in your file."  I've gone through all of my images and none are layered or have transparency. All are 100% opaque .jpg files. Are there any transparency settings that can potentially exist within the fonts?

Thanks, Craig

Which PDF preset are you using? PDF/X-1a:2003 (based on PDF 1.4) should work as you require, since it flattens transparency.
