* Multisilicone grease for lubricating dies * Tube 20g (comes in very long) * Prevents loose Mylar foil on the side (air bubbles) or loosening foil.
* Clean your moulds regularly with a dry clean household roller. * Then smear a drop or two on the inner sides of the mould (especially the slanted side of no. 2 where you put the backs).
Before buying parts, check whether the original diameter of the Mylar film is suitable for your device:

Technical info on bleed and button format
When you design a button or send in an image, you should take into account 2 dimensions: "button size" & "bleed".
The button size is the size of your finished button. This is the image that you actually see on the front of the button.
Run or Bleed
The bleed is an extension to the button format. It ensures that there are no white borders on the buttons.
The following illustration will clarify a lot:
The bleed is different for all button formats:
button 25mm + bleed: total diameter 33.5mm
button 32mm+ bleed: total diameter 41.5mm
button 38mm+ bleed: total diameter46.5mm
button 44mm+ bleed: total diameter53.0mm
button 56mm+ bleed: total diameter66.5mm
button 75mm+ bleed: total diameter 88.0mm
button 88mm+ bleed: total diameter101.6mm
The following examples explain a lot:
This is an example of a 25mm button with a bleed to a diameter of 33.5mm
Make sure that your image is within the button format so that it does not fall off as in the example on the right.
Make sure that the background colour of your image continues in the bleed so that no white borders appear on your button, as in the example on the right.
Also note that if you use a photo, it should have a bleed. This way you can avoid parts of your button falling out.
Extra cool edges for your buttons?
To get extra clean edges and avoid air bubbles, you can limit the printing to the area where your paper disappears into the inside of the buttons.
For all sizes, this white edge is slightly different (and the small sizes do not suffer from it):
38mm > total diameter from visible zone to white edge: approx. 40.50mm 44mm > total diameter from visible zone to white edge: approx. 46.50mm 56mm > total diameter from visible zone to white border: approx.59.00mm 75mm > total diameter from visible zone to white border: approx. 79.90mm
PS: When we make the buttons you don't have to take this into account. We place this border automatically.
