    Control of lighting is critical as the latitude of the paper is quite low:

    Latitude is very low in color papers. Nevertheless these are excellent photos. Congratulations.

    So have you tried contact-printing them?
    I know there's printing on the back, but even with a bit of text I'd be interested to see how well it worked (And maybe a nice go at the backprinting with a bit of steel-wool might solve that problem, if you can scrub exactly the same over the whole sheet so that there aren't thick bits and thin bits).

    What's the filtration like for sunlight, have you tried?
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    No, I haven't I don't have a real darkroom, so it's not an option for me. I suspect it would work, but you would probably need high M & Y values.

    You need lots of magenta and yellow - more than I have (and I have a lot!!). My pics came out very Cyan.
    I'll be getting more Magenta soon I hope, then I can try it again.

    Skin tones came out well, but I have strange problems with dark blues and blacks.
    In this picture (a self portrait!) I am wearing a dark navy blue T-shirt!

    in other examples, my black background has red highlights.
    For my experimentation, skin tones are more critical than dark blues, but this is very odd to me!!
    Any suggestions why?

    It may be critical - the portrait was taken with a studio flash and the following filters:85B-85C-25Y- 20M - could this blue to red shift be exaggerated because I did not use a UV filter?

    UV is important with papers just as IR is. You should use both.

    Thanks, PE!
    I never heard of IR blocking filters before, just did a search and they are easy to find. I wonder if this would help remove the hotspot I have in the centre of the images?

    Color papers are tungsten balanced. As such, they have a lot of IR sensitivity to get them "out there" into the short IR range for matching the films. If you do not filter things properly, colors can be off. This can even happen with films.

    Yeah I've encountered this before, ably answered by PE as well :-D I looked into IR blocking filters but they don't come cheap.

    This one was the one that made me notice it first, this is the corrected scan,


    This is just the red channel, looks very IR
