You can prevent "gas ghosting" - the light haze that can occur when you frame an inkjet print under glass - by following these steps.
1. After printing, allow your print to rest in the open for 15 minutes
2. Now, lay a piece of plain copy paper on top of your print for 24 hours. The plain paper will absorb the ink solvents and speed up the drying process
3. After a full 24 hours check the plain paper to see if it looks wavy. If so, it means the paper is still absorbing ink solvents. Place another sheet of plain paper on top of your print and wait another 24 hours.
If the plain paper is flat, and not wavy, then your print is ready to be framed.
If you find a framed image with a light haze on the inside of the glass, then your print is still out-gassing. Remove the print, do the above steps, clean the glass, and reframe the print.
