Can you print both sides without the impression showing through?
When printing double-sided cards, invitations, etc., we take care to make sure the impression does not punch through the opposite side by adjusting the amount of impression for the stock thickness and using a hard packing behind the piece on the tympan.
Depending on the character of the stock, there will be a certain amount of change of texture, as the fibers in the high-touch surface are flattened against the tympan by the impression. There also be some flattening of any prior impression opposite the side being printed. In practice, this is rarely noticeable, but the designer of double-sided work should be aware of it.
On our high-touch double-thick stocks (220# / 600gsm), we take full advantage of the thick, compressible fiber for deep impressions, including "blind" (inkless) impressions. But even on single weight stock (110# / 300gsm), we get very good results from inked impressions.
