  1. Two things to try.

    First reset your permissions - use your install disk and after you boot from the CD go to the

    utilities and select reset permissions.

    Second reset your pram by restarting your mac and when the black screen comes up press

    the apple - option - p - r keys all at once and hold them down until you hear the second

    bong and then release letting the computer boot. Hope this works for you.

  2. In Vuescan click Perf and under it will be a box for External viewer. Check the box and a

    selection box appears which is probably on default. Change to what ever program you

    would like to use as a preview. If you don"t want a preview then deselect the External

    viewer box which is what I do when scanning large amounts of slides. Without the viewer

    the scan will be written to disc.

     

    On the second problem I agree that you should scan at the highest dpi to get the most

    information from your negatives. As far as the file size check under the Output that the

    TIFF box is checked and not the JPG box.

  3. First let us define what an ink is - a fluid that has a colorant (pigment or dye) + binder +

    solvent ( water or carbon based) + additives.

    Pigment is a dry powder - dye is soluble is the solvent.

    Binder holds the pigment together and sticks to the substrate.

    Solvent controls the viscosity of the ink.

    Additives help the ink wet out the paper, film, and foil.

    Ink jet printers usually use water based ink which will wet out and adhere to paper and

    some films but will not wet out and adhere to foil substrates unless they are treated.

    Solvent based inks (hydrocarbon, alcohol, ketone etc. ) will have better wetting and

    adhesion to foil substrates.

    A pigment ink can be water based or solvent based and is much more permanent than dye

    based ink. Pigmented ink would be recommended for outdoor use and probably should be

    coated with a good UV resistant clear.

    If you want to use the Canon printer then you will have to find a foil that will accept the

    Canon ink ( wet and adhere to it ).

    Hope this helps.
