Lap register

Registration, Continued No register Loose register Lap register With no register, each color or plate prints independently or without relation to all other plates. It does not require registered overlays, merely instructions to the printer. Loose register is used for images not requiring highly accurate placement of the color portions. You make a separate overlay for each color and key this overlay to the master art. Simplicity in the master artwork is paramount. Lap register permits a slight overlay in the separate colors or plates. This simplifies the DM's task in creating the overlays and eliminates white gaps or spaces which occur if the registration is off. Colors of similar densities that overlay form a black line, while lapping patterns or textures requires you to draw a red line between them to avoid moire. Figure 1-44 shows lap registration.

Save this registration technique for full color or full color continuous tone art. 1-60
