We printed our paper inserts and sprayed them with an extra-fine mist hairspray to set the ink. We let the inserts 'cure' for several days before use.
When pouring the first layer, we let the soap cool down some before pouring and then pressed the inserts in place when the soap began to form a 'skin'. Since the paper inserts were water-soluble, we could not spray alcohol between the two layers to help bond the soap.
Instead, we let the first layers sit and cool for almost an hour before pouring the second layer...which we did the same way--letting the soap cool down some before pouring it.
We discovered that by waiting and letting the soap cool down before pouring, the ink did not run...and the soap remained clear/white instead of evidencing yellowing. Higher temps always resulted in the ink smearing and discoloring the bars. The lower temps produced extremely clear soap plus the bars seemed to 'hold together' better (no coming apart at the layers).
The extra effort does add significantly to production time but it was well worth it in the bars' final appearance - the company's logo and tag line were very clear and the soap looked like glass.
