Hi @ all, I had to notice, that the colours of my paper models loose intensity by getting older. I use 250g/m2 ink-jet paper and an inkjet printer to print my models. I am drawing portraits, too. To fix the coulour of these drawings I use a fixing spray to fix the drawing. Now I was wondering if there is an idea how to fix the colours of the paper models. Any idea would be very welcome. Best regards and thx in advance.
