question about mimaki printer and postershop rip

[Stephen Morriss]

you only need files at around 160 dpi for the maximum quality, then at about 6ft viewing distance 100 dpi and down to 72 for over 10ft distance.

These are a rough guide so you can mess with it. I’ve never had any better results from a higher resolution that 160dpi though, even on small photo’s printed on a photo printer.

I’ve just printed a 2m X 850mm poster for a client on my hp3000 (old printer 600dpi) and the file was a 3mb jpg, result is very good, by 18" away you’d never tell, I normally use jpg without compression and the file size is usually around 15mb but this had to be done quick and it had to be emailed easily.

P.S. I know dpi isn’t the proper term but it’ll do.

I always thought a file for printing had to be 300dpi or higher. I am going getting stuff printed by someone else (in china) and their ads have 1440dpi and 720dpi but when you have a file at that res you quickly go into the GB with file size.
Am i right in thinking now there is no need for such a high res and corresponding file size?

[Stephen Morriss]

Printer resolution has little to do with the image resolution, most print shops ask for the file at 300 dpi half size or just 300 dpi, try sending a high dpi image to your printer and then send a 160 dpi image printed at 1 to 1, bet you’ll see little or no difference.
Take it upto 180 if I bet you’ll see no difference, so on an image that’s not being looked at closely why go higher?

You could edit the detault quickset. I’m pretty sure there should be resolution controls there.

Also, when you setup a new media (media manager) you should be able to tell it what type of resolution you plan on working with. You will also be able to tell the rip what type of screening you would like.

Can’t be too specific here as I don’t have a Mimaki printer.

The people fron Onyx do have tech support…

Good luck.

Unless you have a profile setup for that resolution and media, then you shouldnt be changing the settings at all, it will produce some results that are pretty average, with both colour and quality.

Actually, i get the feeling your talking about image res and not printing res. If this is the case, you cant adjust the image resolution in postershop as far as i know. Thats a job for Photoshop. If your images are vectors, then there is no need to worry about dpi as they can be increased without loss of quality through preflight. This can often save processing/ripping time too!

I wanted to say thanks to everybody that answered my question it helped out alot…

Thanks Again,
