Official Support Channels & Response SLA

What to Include for Fast Technical Assistance

Because Rasterbator.app processes images entirely within your browser memory using HTML5 Canvas APIs, technical issues are often connected to browser hardware acceleration, device memory limits, or printer driver scaling defaults.

To help us resolve your issue promptly, please include the following details in your email:

• Browser & Operating System: For example, Chrome 126 on macOS, Edge on Windows 11, or Safari on iOS.
• Tool Page Used: Specify whether you encountered the issue on the Poster Maker, Wall Art Generator, or DPI Calculator.
• Paper Size & Grid Dimensions: Mention your selected paper format (A4, A3, or US Letter) and grid layout (e.g., 3 pages wide by 4 pages high).
• Image Resolution: The approximate width and height in pixels of your uploaded source image.
• Error Symptoms: A brief description or screenshot of any error messages, blank pages, or unexpected visual output.

DIY Printing & Assembly Guidance

If you have questions regarding paper weight, seam trimming techniques, or adhesives that won't damage drywall, please check our comprehensive Step-by-Step Poster Assembly Guide before writing. Most common issues—such as distorted aspect ratios or mismatched tile borders—stem from printer dialog settings defaulting to “Fit to Page” instead of “Actual Size (100%)”.
