Helpful Design Tips
-
Begin with selecting your grid type, and enter your tag, marker, or checker size.
-
Always use the default "Calculated Board Size" option. This feature provides you with an even symmetrical board with enough white spacing around the markers, allowing for easier detection.
-
Adjust the number of columns (left to right) and rows (top to bottom) to fit within your desired field of view.
-
FoamCorePrint allows customers to upload their own files for calibration targets. However, we suggest that customers use our online tool to place their orders to ensure optimal results.
Frequently asked Questions
Can I download a printable PDF file of my design?
Once you've completed your design, we highly suggest you save the file and try printing your design at home. Additionally, you can measure your downloaded PDF document to confirm its accuracy. Please Note: Be sure to disable any page scaling when downloading PDF files to print on an inkjet printer, as this confirms your printer driver does not apply any scaling to your document. This process will ensure your new checker design properly matches your application's use.
