Vector graphics are distinct from pixel-based graphics (raster images). Instead of being composed of individual pixels, vector graphics use geometric shapes like points, lines, and curves, which are defined mathematically. This allows them to be resized without any loss of quality, ensuring they remain sharp at any scale.
Why choose vector graphics?
-
Scalability: Resize images as needed without compromising quality.
-
Flexibility: Adjust colors easily after uploading to the Spreadconnect app.
-
Efficiency: Files are smaller because they store only the mathematical definitions of shapes.
Vector graphics are particularly suitable for plot printing, a high-quality method used in flex and flock printing. Plot printing ensures clean and precise designs, making it ideal for T-shirts and other products.
Plot Printing Process
-
Design Preparation: A plotter cuts the design from colored printing foil.
-
Excess Removal: Unnecessary foil is manually removed.
-
Heat Pressing: The design is transferred to the product using heat and pressure.
-
Finalization: The backing film is peeled off, leaving the finished product.
This process works best with vector designs that use simple, geometric shapes and minimal colors.
Requirements for Plot Printing
For your vector designs to print correctly, they must meet the following specifications:
| Requirement | Details |
| File Types | .ai (up to version C18) or .svg (no CSS styles). |
| Design Size | Minimum: 10x10 cm. Maximum: 38x38 cm. |
| Line Thickness | Minimum diameter: 1.5 mm. |
| Colors | Maximum of 3 colors, placed on separate layers. No gradients allowed. |
| Curve Closure | All curves must be fully closed to avoid errors during cutting. |
| Paths | All design elements (including text) must be converted into paths. |
Left: Vector graphic with color gradient - only possible as digital print, not as a flex and flock print.
Right: Vector graphic without color gradient - we print flex and flock.
Measuring Line Thickness and Gaps
-
Use a 1.5 mm diameter circle to check the thinnest lines in your design. Ensure the circle fits entirely on the line.
-
Use a 1 mm diameter circle to verify gaps between design elements.
If lines or gaps do not meet these requirements, adjust the design accordingly. Remember, reducing a design’s size later can compromise these measurements.
Creating High-Quality Vector Designs
Closing Curves
Ensure all curves are fully closed. Open curves can result in unintended straight-line connections during the cutting process. Use the "Combine" or "Merge" functions in your design software to close curves.
Converting Objects into Paths
Convert all elements, including text, into paths. For example:
-
In Adobe Illustrator: Go to "Type" and click "Create outlines" (Shift+Command+O on Mac)
-
In Inkscape: Use "Combine" or "Convert" to ensure objects are properly embedded as paths.
Recommended Tools for Vector Design
-
Adobe Illustrator: A professional tool for advanced vector design.
-
Inkscape: A free, open-source alternative that offers robust features for vector creation.
Advantages of Vector Graphics
-
Perfect for Simple Designs: Best for logos, text, and graphics with up to three colors.
-
High Compatibility: Works well with flex, flock, and digital printing methods.
-
Infinite Scaling: Maintain sharpness at any size.
