New with Quark.Images problems 1

[skinlab]

I am using Quark from a couples of days I'm a little confused with some things.
1.Wich format should the pictures have(JPEG,TIFF) and wich resolution for professional printing?
2.Pictures in RGB or CMYK?
If you could explain me in details from the start till the end the creation of a Quark document ready for professional printing.Thanx a lot friends!

If you are preparing files for print, e.g. magazines, books, leaflets, etc. then use CMYK files at 300 d.p.i. and save as either EPS or TIFF.

JPEG files utilise 'lossy' compression - this means that the picture will degrade, depending on the compression level used, and therefore jeopardise the final print result. This scares alot of people.

RGB files are really intended for 'composite' output - e.g. for the web / inkjet output, etc.

... however - despite all I have said above - I own a reprographic (scanning) company. I use EPS files with JPEG encoding rather than Binary. This makes the files about 1/10th the size of the original picture file and makes them as fast as lightning. I have never had anyone complaining about the quality of an image. They output at an astonishing rate. I just keep the quality on the high/maximum side.

You're the man Duncan.Thanx a lot

regarding images at 300dpi...

yes.. 300dpi but at 100% enlargement
If you start enlarging the image in Quark the resolution effectively goes down.

It might seem obvious but I am always running into people who just don't realise that.

Tiff,EPS, DCS

CMYK, Monotone, Duotones, Tritones, Grayscales

For "professional printing" use:

- images that are 300dpi (at the size you have them in the document).

- CMYK for colour, grayscale for mono and 1200dpi bitmaps for linework.

- I like TIFF's (with LZW compression), but EPS files are OK too. Try and steer clear of any form of JPEG compression as it can cause problems at output time.

There is really too much to go into regarding how to "explain me in details from the start till the end the creation of a Quark document ready for professional printing".

The site you linked to states "Preparing artwork for a perfect press-run". If that is you, and you are asking these questions, I would think about changing my tagline.

Foamcow:
I think Bodes is quoting the original post (I had to look twice too). BTW * for explaining about effective resolution - I'm sick of trying to explain this to some of our customers

Bodes:

Oops.... yes sorry Bodes
LOL

And thanks for the *

I am so bad at reading posts...when I am in a hurry. Perhaps you should take the * away
