How to make a protest sticker!

To support protests against the climate crisis, in addition to public protests, banners, etc, protest stickers are another medium to make your message visible and literally  “stick”. Their advantage is that stickers can be distributed without causing to much attention, e.g. at a public place, without having to expect negative consequences for the protester. Stickers are also a nice give-away to passengers, esp if they are visually appealing. Here, I would like to present a short tutorial how to design and print protest stickers. It is a work flow which I tested and worked for me:

  1. Design the sticker using LibreImpress!
    Note: I recommend using a computer because the design can then be easily updated, shared, multiplied, etc!
    Note: Read the printing requirements (e.g. file format, file size, resolution, color model, …) of your selected printshop and apply it to your design! Example: Flyeralarm Printing Guide
    Example: Bend the carbon curve! [ODP, RGB color model]
  2. Export to PDF format with a resolution of 300 dpi from LibreImpress
    Example: Bend the carbon curve [PDF, RGB color model]
  3. Import PDF to Krita drawing program
    Note: Printshops often require the CMYK color model to avoid colours, which are unexpected by the unexperienced customer who design their drafts on a screen using the RGB color model.
  4. Convert Image from RGB to CMYK colour model using
    Krita > Image > Convert Image Colour Space > Model: CMYIK/alpha with default settings (Depth: 8-bit integer)
  5. Adjust image size to printing requirements using Krita > Image > Resize Image > New size, Offset
    Note: The color and file format conversion may lead to small (a few millimeter) changes in image size, which should be corrected for optimal print results and avoid complaints by the upload filter
  6. Export Image as TIF with default settings:
    Example: Bend the carbon curve [TIF, CMYK color model]
  7. Select size and number of stickers at Flyeralam printshop. I selected Vegan Stickers, round, diameter 9.5 cm, white paper, 4 colours, 250 copies, 4 colors, 623SEK [ORDER NOW!]
    Note: The offer by Flyeralarm was the best quality at lowest price I could find!
  8. Upload the file in TIF format with CMYK color model!
    Example (same file as in #6): Bend the carbon curve [TIF, CMYK color model]
  9. Approve and submit to printing!
  10. Delivery (in Sweden) after about 1 week via UPS!


Note: I recently received the printed results from Flyeralarm and I am happy with quality of the stickers and delivery! Regarding the design, the details are readable, but rather small, and the contrast of the Carbon concentration plot in the foreground and the blue marble earth in the background should be stronger. Rest is fine! I consider it a success as my first sticker project.
