A register punch is a tool used in photography and printing to create small alignment holes in film, paper, or other materials. These holes help maintain precise positioning when overlaying multiple images, ensuring correct alignment and preventing shifts or misregistration.
Register punches are especially useful in traditional film processes, multi-layer printing, and animation, where accuracy is critical for maintaining image sharpness and consistency. By using register punches, photographers and printers can achieve professional-quality results with perfectly aligned images.
