    In addition, some kits still use CD4 as developing agent. I will keep warning of this. That developer seriously degrades both the dye hues and dye stability (particularly dark stability) of the images. If a kit uses CD4, do not use it with any current color paper from any manufacturer, as they are designed for CD3.

    Kodak RA-RT is cheaper, but I wouldn't call Paterson's Printmaster RA developer grossly overpriced. The Kodak 10L kit costs makes $23. The Printmaster product, which also makes 10l for high-temp processing, costs $15. Of course, it only makes 5l if you're doing room-temperature, but the processing times are shorter, listed at around 1 minute. I usually extend those times to 90 seconds for better consistency. Rowland Mowrey recommends 2 mins for room-temperature RA-RT.

    Printmaster uses CD3.

    The ratios printed there are the same you quote.
    I use a Nova processor too, and I think that tetenals has the longest life when stored in nova processor with tubular lids. This means the shelf life, not capacity as I tend to spend chemistry more by storing it too long.
    When developer gets old (weeks in the nova processor), I get brown whites despite of replenishing. This is cured with a fresh batch of developer.
    In nova I have always "replenished" by changing part of the developer solution with "initial tank solution" mixed with starter when I start a printing session.
    Many thanks for the information. Until your reply I had not noticed that the label was thicker than the one on the starter bottle and it can be opened without damage but only if you are very careful. Ilford do the same on some of their B&W chemicals but it is easy to damage the instructions.

    No need to write to Paterson now. The great thing about APUG is that no matter what the problem, somebody will have the answer you need.
