I am a very committed drawer and sketch artist, so I obviously have piles of sketchpads and sketchbooks. The only problem is that the graphite/charcoal from my 2B sketch pencils smudge on the papers above it. This is very annoying and inconvenient. What can I do to stop this?
Fixatives are the best. Try them on the sample sketch and also you need to know how much to apply.
Keep a trace paper on each page of your book. Use sellotape to stick the top border with paper so as to avoid the moving of trace paper. Graphite does not stick to the glossy surfaced paper.
You can also keep any other slick surfaced paper like photo printing paper or transparent book cover or laptop's screen guard. Stick the top border with the paper.
Common method is aerosol hair spray, but I do not recommend this because over the time paper will fade and turn pale yellow. Ruined many of my drawing sheets.
When applying fixative sprays, do it outside or ventilated area as they are very toxic in nature. Many types are there, mainly 1. workable(spray while drawing) and 2.non-workable(post completion spray), they are glossy.
Also I suggest if it is worth saving, put them behind glass.
