Transparency question 2

[Thingol]

Hi All,

I'm relatively new to InDesign, so don't be too hard on me! Here's my question:

I have a Master spread with a bitmap image covering the entire left page. I have made another master page based on the first master page. On this one I want to add chapter numbers, which I want to be transparent. When I select the chapter number's text frame, and set the opacity to 70%, the text frame becomes transparent. The problem is: the background image in the first master also becomes lighter (i.e. gets a 70% opacity?)

I have been trying to find an answer to why this happens, but haven't had any succes yet. Has anyone here got a clue what I might do about this?

Thanks a lot.

Best regards,
Martijn Senden.

Note:

The image that sits at the background of the text frame (i.e. on the first-mentioned master spread) does not get a 70% opacity. Instead it turns a bit lighter when any transparency is set for the text frame. This amount is constant, i.e. when the trancparency of the text frame is altered, the image keeps the same brightness (except when a opacity of 100% is chosen, then the bitmap turns to it's original brightness again).

Anyway, the question remains: who can help me out with this? Thanks a lot in advance for any help!

Best regards,
Martijn Senden.

This is nothing more than a sort of glitch in InDesign. It does not affect you're actual printed quality.

Hope that helps,

Ok, so ,y prints won't be affected?

Unpractica;, I hope they'll fix it! But thanks a lot for the answer. I'm glad I wasn't doing anything wrong.

This may not really be a glitch, but rather a way that your preview preferences are set. You will notice in the pages palette that some page icons have a checkerboard. This checkerboard indicates that transparency is used on that page. InDesign takes extra resources to display the transparency effects on screen. Less display resources are used on the pages without transparency. If you want to even everything out, go to your View menu and set the display to show overprint preview. This might make the appearance of the large bitmap more consistent as your work. ...but it will also slow things down a bit since you are asking InDesign to use more display resources.

If you find something that does not seem to be working correctly, don't just say 'I hope they fix it' in a user to user forum that Adobe does not read. Adobe.com has a place to report bugs.

This, though, may not be a bug but just a display option issue.

Ok, I tried this, but the problem still occurs. I think I had tried this myself before as well. Anyway, the document has already been printed and it came out of the printing process the way it looked on screen when I set the opacity to 70%. Strange, but true.

Anyway, I wasn't trying to report a bug at all. I'm not even sure it is a bug or not. And if I would have, I'd have done so with Adobe of course.

Martijn.

Has the background bitmap got any spot colours applied? My experience is that if you have transparency against spot colours, then the overlap between the spot colours and the transparency do some crazy things - like the lightening of the background element on screen and/or in print.

Hi Eggles,

Thanks for the input. I'm not sure. I don't believe there are any spotcolors involved, bu I may be wrong. It is a .jpeg from

http://www.stockphotos.com,

which I converted to grayscale in Photoshop.

No spots likely in that greyscale JPG.

This is a long-time (since ID 2.0 at least) issue I've had, too, and I've seen it complained about many times both here and on the Adobe forums. If I put some kind of transparent thing on top of an image (including a PSD file), the image changes colors... and not just under the transparent thing (which I could see as me somehow screwing up by accidentally appling a tint to the background or something), but to the entire image. The shift is not consistent, and I have no idea how to fix it. As such I have to rejigger the color balance of the image below to get it to come out right at press, and it's frustratingly hit or miss.

Dunno.

There's several good resources (including two PDFs directly related to transparency issues) on the Adobe wedbsite here:

Most excellent, thanks.
