    Hi folk

    I have scanned an old book that needs reprinting which has mainly text but also some integrated half tones. I have scanned the pages as line work and then rescanned the relevant pages with half tones as greyscale, 79 pixels per cm (may be it needs more pixels) with a descreen option chosen.

    I need to replace the pictures that i scanned as line with the greyscale ones. Lead me through what i have to do – brain is giving up!!

    Wow. Well, one idea is to place each lineart page on an InDesign page, then place the halftone image over that, covering up the original. (Make sure the grayscale halftone image is in a frame with a fill of Paper, so it covers up the background image.)

    David, I’m not sure that is what Nigel was looking for. I suspect he wants to REPLACE the images, rather than cover them up. After all, he did say he rescanned the relevant PAGES with the half tones, not just the half tones themselves.

    The way to replace the page images is to select the image that needs to be replaced (just click on it in the InDesign page with the black arrow tool). This will highlight it in the Links panel. Then use the pop-out menu of the Links panel to Relink… Navigate to the rescanned greyscale image, highlight it in the dialog box, click Open and your job is done (apart from clicking OK in the dialog box that quibbles over a different file name).

    Or at least your job will be done if the two images are the same size. If not, then you may need to adjust the frame edges and the fit-to-frame characteristics (using the little icons in the control panel).

    Mind you, if I was doing it, I would have rescanned just the half tones, not the whole page they were on, and used David’s method.

    Right i have got somewhere, after i scan on my HP Scanjet 8300 i have the ability to crop the subject that i have scanned so i just crop to the picture that i require and send the file to a pictures folder.

    After i have taken all the original scanned pages into Indesign i create a rectangle image frame over the original picture, then in swatches choose the paper option and it blanks out the original image. I then choose file, place and pick the descreened scanned image and then tick show import options and replace selected item, click OK and the image goes into the box.

    I then adjust the image just to make sure it is positioned correctly and hey presto it works

    Thanks for the tips, it gets the brain working again!!
