    Just bought an Olympus mju mini for work. It's small, has flash, digital and optical zoom, a million program modes and is weatherproof, perfect. To go with it I have bought a dedicated photo printer for producing 6x4 prints which I can attach to paperwork for onward submission to my customers. Given the plethora of resolutions on this camera, what would the best res be for prints this size given that I want to maximise the number of shots I can take? Is there any advantage in taking higher res shots for 6x4 prints? I've checked the beginners sticky but it doesn't really answer my question. By the way, if there is a table available of ideal image resolutions for a given print size I would be grateful if someone could point me in the right direction.

    Use the 1600x1200 setting as that is a 3:2 ratio better suited to 6X4 printing :)

    The first question is what resolution can your printer go to?

    No suprise there then :laugh:

    You can get acceptable photo quality prints at 200ppi (higher the better obviously) but he'll perhaps need to experiment to find the resolution that he finds acceptable.

    The printer is an Epson Picture Mate, the box claims 5760 dpi but I think that might be a fudged figure. Piccies look OK if a little low-res and blocky, hence wondering if I should be using a more compatible resolution when taking pictures. Can't you tell I'm a noob!

    As zone says you want to be at at least 200 DPI - i.e. 1200 x 800 for a 6x4 photo.

    The thing to bear in mind of course is that digital cameras are inherently at "computer" resoultion (6x4.5) rather than photo resolution (6x4) so some cropping may also occur.

    Spec sheet has it down as 5760x1440dpi, this is actually 360 x 90 dpi with it being an inkjet, this is probably why the end product looks a little low-res/blocky, you'd perhaps have been better going with a dye sublimation printer if overall quality was paramount such as one of Kodaks easyshare printer docks.

    For the simpletons of us around here can you actually explain why?

    Read it somewhere I'll have to go have a look but what I remember is.

    In relation to a sublimation based photo printer running at 300x300dpi an equivelant ink jet would need to print at something like 4800dpi, a multiplication of 16 to give comparable levels due to the need for dithering.

    Probably the poor way I explained, but I just reversed the equation dividing his dpi figures by 16 to get to 360/90.
