BannerLab User Guide: design, export, and check
Use the browser editor to arrange a draft, then check the exported file with your print provider. A download is not automatic approval for production. These instructions distinguish the canvas, the image inside it, and the final physical print.
1. Start with one message
Open the banner editor, choose a background and add the main message. Put dates, eligibility conditions and location in separate text objects so you can adjust their size independently. Ordinary design editing does not require an account.
If the online background or font list is unavailable, the editor provides a basic background and system font. This allows you to start a draft; it does not mean every remote asset is available offline.
2. Arrange text, images, and shapes
Drag objects to position them. Use your own photos or logos only when you have the right to use them. A solid shape behind a heading can separate the words from a busy photograph. Compare two drafts with the same background and change just the heading or color to see what that change does.
3. Separate dimensions from zoom
The size controls in the English editor define its output dimensions. The Korean editor uses a fixed 1,600×960px workspace and separate background sizing. Zoom changes the view, not the physical print size. A pixel value alone does not specify centimeters.
When resizing a photo, preserve its aspect ratio unless you intentionally want distortion. Check the entire exported canvas, including any white margins, and tell your printer which area should be printed and the intended finished dimensions.
4. Know what each export contains
- SVG: may contain vector shapes and text paths, but imported raster photos remain raster. Font processing can fail; inspect the exported lettering, especially when a system fallback font was used.
- Banner PDF: is converted from SVG, with an image-based fallback. The extension does not guarantee every element is a vector or that its physical page size matches your order.
- JPG: is a rendered image of the design. Rendering more pixels does not recover detail missing from the original photo.
- Business-card PDF: contains a JPEG rendered at 300ppi. It is not an editable vector original.
5. Calculate image resolution at the placed size
Use pixels ÷ (print centimeters ÷ 2.54) for each direction. For example, a 3,000×900px image stretched across 300×90cm has 25.4ppi in both directions. The appropriate target depends on your printer, material and viewing distance, not a universal number for all banners.
A logo placed in a smaller region needs its own calculation. Ask about cropping, bleed, color conversion and finishing. A screen preview cannot certify print color or distant readability.
6. Save and re-open before ordering
Download important versions before closing or refreshing the editor. Open the final file and check spelling, dates, phone numbers, font substitutions, image edges and blank margins. Confirm the required format and finished size with the print shop.
Other tools and their limits
The business-card editor uses a 90×50mm finished size with 2mm bleed on each side. Background removal can erase white pixels or similar colors connected to the image border; it is not semantic AI object segmentation and can also remove parts of the subject.
The MiriCanvas helper (Korean) is a separate Windows download, not a browser-only editor. Read its requirements and third-party service conditions before using it.
