Printing Quality:The CafePress printing quality and paper quality are very good. The posters look great. They have a resolution of 6000x4000.
A 100x100 pixel snippet of the full 6000x4000 image of The Periodic Table of the Elements in Pictures is shown below — that's 0.5 inches square on a 30 inch poster.
Printing Quality on T-shirts: CafePress uses a plastic film transfer process, so the print resolution is very good (even the fine print is readable), but the image area does not feel as soft as the rest of the shirt.
PROBLEMS? If you have any problems with your order please use the CafePress Customer Service links at the bottom of the CafePress Wlonk Shop page. CafePress does all the printing, mailing, and financial transactions. If the product is defective, CafePress should send you a good one or give you a refund. If you feel like it, you may also email me, the author/artist, at firstname.lastname@example.org, just to let me know. I usually can't help you with your individual issue, but I'd like to be aware if a general problem arises that affects multiple customers.
Alternative: You can also download and print the PDF file as a poster at your local print shop (like Staples.com) or on your school's or company's poster printer.
