Printing guides
Check paper, scale and joining before spending a full stack of paper.
Print one large image across several sheets
You need an image, a home printer, matching paper and a PDF reader. Rasterbator Studio creates the individual pages; the reader should print those pages once, without tiling them again.
Trim and assemble a tiled poster
Before cutting, lay out the sheets on a clean flat surface and identify the assembly style. A continuous picture, intentional white grid and whole-sheet collage need different treatment.
Print a poster PDF at Actual Size / 100%
The PDF already contains the paper-sized tiles. Your job in the print dialog is to preserve their dimensions, not to fit or split them again.
Printer margins, overlap and borderless output
Three spaces are easy to confuse: the printer margin protects the edge of each sheet, overlap repeats image content for joining, and a white divider is part of the design.
How many pixels does your poster need?
Choose the finished size and viewing distance before deciding whether an image is large enough. Pixel count is useful, but a sharp original and a test print matter more than a “300 DPI” label.
What is rasterbation, and when should you use dots?
Rasterbation turns an image into a large graphic made from marks such as dots. From nearby you see the pattern; from farther away the marks combine into light, shadow and recognisable forms.
Choose paper, exact dimensions and the right page count
Paper size is the size of one sheet. Finished size is the assembled poster. Set them separately: a 60 × 90 cm poster can use A4 sheets without requiring a 60 × 90 cm printer.
Rasterbator alternatives: compare complete print workflows
Choose a replacement by testing the image, page layout and final print, not by counting effect names. There is no single best workflow for a photograph, a PDF drawing and a decorative dot portrait.
Alternatives to Block Posters: choose by the output you need
Before replacing a block-poster tool, identify the problem: awkward proportions, unwanted white bands, a missing visual style, or a need to combine separate photos into a document. Those tasks call for different workflows.
