Good question. Rollers are indeed used, there are several differnt sizes and are very soft. They will remind you of your girlfriends 38DD's. You pick up the ink or woodgraining on the roller then just use light or heavy pressure depending on the shape of the surface you are "printing". You start and stop on 220 grip paper turned grit down. On a compound curve like garnish molding you start your inking with let's say the upper 1/2 of the roller. You go one revolution of the roller, then rock the roller to the bottom 1/2 and return. Once you get the hang of it you will not believe how good it looks. Large or wide surfaces where you would have several parallel lines of ink you again use the sandpaper. You just put it down over the fresh ink and then you have a straight edge for your next inking line. This process, according to "Grain-it" was used by just about all the car manufactures in the US from the '20's to the '60's. They get around $1200.00 to do a dash back to orginal for you, so I decided to try it myself with one of their kits.
