If you take a grid paper the grid will become part of your art, but does Karbon print the grid which you can have it show (except possibly via an option)? > > In drawing applications, the canvas is NOT part of your art, but simulates the canvas you'll be printing on. It's a backdrop layer that sits behind/below the lowest layer you can draw on. If you plan to print on a coloured piece of paper, or one with a canvassy texture, you'll probably want to adapt your virtual canvas so you can incorporate the physical canvas properties into your design. But you don't want that virtual canvas to print as that would be a waste of toner at best... That is actual a valid point, although in say Krita with transparent pixels a checkerboard is shown. That said it might make more sense for this "testing background" to be part of the document and not a general setting - if the use case is as you say then the testing background would also be different for different projects > That's not to say that the virtual canvas should not be exportable at all: you'd want to be able to include it when generating a PDF (SVG, JPG, etc) format version for use in on-screen only presentations. Of course you could just add a backdrop layer in that case. > > I'm not aware that Karbon has the equivalent of a slide/page design feature where you can define how each page will look. That could look be used to be achieve what I describe here but in Karbon that layer should probably not be printed by default (just like it isn't in presentation apps, IIRC).
