Digital Graphics

Raster V.S. Vector + Advantages and Disadvantages

Raster Graphics: Made of pixels (tiny dots of color). They are best for complex photos but get blurry when you zoom in.

• Pros: Great detail/shading.
• Cons: Large file sizes, lose quality when resized.

Vector Graphics: Made of mathematical paths (points and lines). They stay perfectly sharp at any size.

• Pros: Infinite scaling, small file size.
• Cons: Hard to make look like a realistic photograph.

How Digital Graphics Are Used in Production

1. Vinyl Sticker Workflow

• Design: Create a vector graphic in Inkscape using shapes or drawing tools.
• Preparation: Convert all text to paths to ensure the cutter recognizes the outlines rather than the font file.
• Export: Save the file as an SVG (Scalable Vector Graphics) for compatibility with the cutting software.
• Cutting: Send the design to the vinyl cutter, which uses a small blade to kiss-cut the design into the adhesive vinyl.
• Finishing: Weed the vinyl by removing the unwanted negative space.
• Then apply transfer tape to lift the design and prepare it for application.

2. Scanner to Vector Workflow

• Creation: Draw a clean design on paper, typically using dark ink for better contrast.
• Digitizing: Scan the drawing to create a digital raster image.
• Vectorizing: Import the image into Inkscape.
• Use the Trace Bitmap feature to turn the pixels into editable paths.
• Refinement: Clean up the resulting vector paths by deleting unnecessary nodes or smoothing out rough edges.

3. Large Poster Printing Workflow

• Layout: Design the poster layout in Inkscape, ensuring the canvas size matches the intended print dimensions.
• Quality Control: Use only high-resolution images to prevent pixelation when scaled up.
• Export: Export the final design as a PNG at 300 DPI (dots per inch) to maintain professional print clarity.
• Production: Send the file to the large-format printer, ensuring the paper roll and ink settings are correctly configured for the specific media type.
