How to print and assemble a block poster
A block poster is printed as separate tiles and joined into one large image. Download the already-split PDF from BlockPoster.ai, print each page once at Actual size / 100%, then trim, align and tape the sheets. Do not tile the PDF a second time in your print dialog.
Start your block poster
Upload a JPG, PNG or WebP, or sign in to generate original artwork with AI. Choose a photo with enough detail for your finished size. Your uploaded source image stays in this browser; only AI prompts go to our online provider.
Size your block poster
Choose A4, US Letter, A3, Legal or Tabloid. Set the width or sheets across, then adjust crop, margins and overlap. Check the page count and effective image DPI before downloading. The preview and PDF use the same layout calculations.
Print your block poster
Download the already-split PDF. Print each page at Actual size or 100%, one page per sheet, rather than tiling the PDF again. Test one sheet, trim the guides, line up overlapping details and tape the backs together. Then enjoy your finished wall art.
Which block poster print settings matter?
Check that your printer supports the selected paper size and margins. Overlap repeats a strip of image for alignment; optional guides show trim positions. A 10 mm overlap is a useful starting point. Effective image DPI reflects source pixels across the finished dimensions, not just the chosen export setting. Print one test sheet before using the full set.
Where can I check block poster printing guidance?
The sources below explain general tiling, overlap and trim marks. Their Acrobat Poster setting applies to oversized, untiled documents. Our PDFs are already split into paper-sized pages, so use one page per sheet instead.
“Cut marks: Add guide marks to each page for trimming overlapping areas.”
“Once they are printed, the pages are pieced together to form the large format document.”
