Hi Petr,

Thanks, likewise David.

Here is a revised artwork for the Oil Pressure gauge. I added the border and changed the aperture to white to make it easier to see to cut out.
I also changed the colour of the numerals and scale to a light tan as best as I could guess. Always happy for "peer review" if anyone sees a need for a correction.

I tried scaling it but my black only laser printer does not allow 4 x 6 paper selection.

Here's how I have done colour decals in the past:

I buy A4 decal paper, guillotine it to 4" x 6" photo size and adjust settings on the printer for thicker paper. I practice with plain paper cut to 4" x 6" to get the sizing right with adjusting the scaling of the image. Once it looks good and the right size on plain paper I print it on decal paper. Inkjet printer decals need a light spray of Krylon to prevent the colours running when soaked in water. Laser printed ones do not need it coated.

In Australia I get decal paper from Decal Specialists in Melbourne. Order 170 gsm size which is thicker. It was about $1.70/sheet for A4. The thinner size is better for modelmaking.

It is actually fairly simple. The hardest part is getting the artwork right!

Good luck to all.

Cheers,
