I want to print an image relatively small - about A4 - on an A3 sheet of paper.
On the print, underneath the image area, I want to add a number.
In Photoshop, I can increase the Canvas Size (coloured white) and the use the Type Tool to create the number.
But, this means that the shade of white will have to be printed too. Right? If so, this will clash with the surrounding paper white, and I don't want this.
So, is there any way of making just the bare number appear on my print and nothing else? Can I increase the canvas size in a colourless way? If the colour I choose is 0,0,0, will this mean that no ink is used on this area of the print?
