I created text boxes with satin effects to make them more attractive. However, the file size is more than double than without the satin effect. Also, it won't let me optimize / downsample in PDF. Please help.
Yes, if you use that kind of an effect, you're creating a transparent object with a rasterized background. The size will depend a lot of file PDF Preset you're using. How are you using the PDF output? (Smallest File size worked well for me in keeping the file size down.)
"Satin" and its related cousins are bitmap effects, and also might use transparency -- the latter will increase the file size if you export to the lowest possible Acrobat PDF version but should not be that extreme for later versions.
Since it is a bitmap effect, there is not much you can do. Is your file size 1-1 related to the number of occurrences of this effect? If you only use it once, is the file just a tad bigger?
You could try to create the effect in an external file (Illustrator, or even another InDesign file that you place as image). InDesign ought to do better if it "sees" the same image is used a couple of times.
Thanks Steve! I saved the PDF setting to the Smallest File size, and it won't let me optimize its size in Adobe Acrobat because of the special effect. The text box with satin effect bring out the message in a very attractive way in our newsletter, but its big file size is not user friendly for opening it up.
Hi Jongware! Thanks for the explanation! I tried saving the individual page as a separate file, PDF them individually, and group them together, the file size is still big. I will consider using less effect in my document.
Best way I found to bring PDF sizes down when you have transparencies on the Indesign page is to take the images into photoshop and flatten them there, saving them as a TIF file and placing that back into indesign to replace your original files. Took one file I was working on from 5mb PDF down to a 1.6mb PDF, without noticable image quality loss.
