Pixels and physical size answer different questions
An image’s pixel dimensions tell you how much image information it contains. Its physical dimensions tell you how large it should be on paper. A file can look crisp on a phone and still print at the wrong size if the app receiving it makes its own scaling decision.
Start with the intended width or height in centimeters, millimeters, or inches. In Stencra, Print / Transfer lets you set those dimensions while keeping the original proportions. New stencils begin at 10 cm on their longest side, so replace that default with the size you actually want.
Changing the physical size does not invent extra image detail. If you enlarge a small reference substantially, inspect the edges and fine marks before treating the larger version as ready.
1. Choose the paper and page layout
Open the final stencil, then choose Print / Transfer. Set the dimensions and units first. Choose A4, Letter, A3, or a custom paper size that matches the paper your printer will use, then review the orientation and placement.
Leave room for the printer’s non-printable margins. A preview showing the artwork inside a page is useful, but the available print area can differ between printers. Review the final print dialog before committing to a full set of pages.
If the design needs several sheets, inspect the tiled page preview. Check how the pages join and keep the same scaling across the whole set. Cropping a page in another application can disrupt that layout.
2. Choose a file format for the job
Print-size PDF is useful when you want to communicate an exact page or artwork size. Stencra’s PDF export retains the selected physical dimensions. Open the file in a viewer that lets you inspect print scaling.
PNG and JPG work well for image-based delivery. Stencra includes physical-resolution metadata, but another app may ignore that information and choose a size of its own. Confirm the dimensions in the application doing the printing.
Transparent PNG preserves the ink without a solid paper background, which is useful when placing the design in another layout. Transparency does not tell a printer what size to use.
Keep the original export. Sending a screenshot or copying the image through another app can change dimensions or compression. Use the exported file when size and detail matter.
3. Check the printer’s scaling setting
When the file is already prepared at the intended dimensions, look for Actual Size or 100% in the software that prints it. Options such as Fit, Scale to Fit, or Shrink to Printable Area can change the result. Exact labels and available controls depend on the printer and print application.
If actual size would clip part of the design, choose a larger paper layout or use tiled pages. Reducing the artwork to fit a smaller sheet changes its physical dimensions, even if the result still looks proportionate.
AirPrint support depends on a compatible printer. Some transfer printers require their manufacturer’s application or another file-import workflow. Stencra prepares artwork and print layouts; it does not make every printer directly compatible.
4. Confirm orientation and mirroring
Different transfer workflows can handle orientation differently. Follow the instructions for your printer and transfer materials, and find out whether another step already mirrors the image.
Double mirroring returns a design to its original orientation. This is especially easy to miss with a symmetrical motif. Use a readable word or another clearly asymmetric element when checking the process, and verify the final intended direction before use.
Keep a clearly named, readable master design in your library so you can return to it when making a different print version.
5. Measure a paper test
Print a test on suitable ordinary paper before using transfer supplies. Measure a known width or height with a ruler, check that the edges are not clipped, and inspect the smallest important gaps and marks.
If a design set to 10 cm measures 9.5 cm, the workflow has applied 95% scaling somewhere. Check the export dimensions, the receiving app’s size controls, and the printer’s fit settings. Correct the source of the scaling instead of repeatedly guessing a larger size.
Use this final checklist:
- The measured dimensions match the design.
- The full artwork fits within the printable area.
- Lettering and asymmetric details face the correct direction.
- Fine lines and spaces remain readable.
- All tiled pages use the same scale.
