    Non-DI RC papers?

    I see that Photomek..whatever Varycon has no developer incorporated into the emulsion.

    Are there any others?

    I've also picked up on assorted web pages that the glossy version of Varycon is not so glossy. True?

    Thanks!

    I don't think there are any DI papers left - those were made for rapid processing in high-volume labs, which has been completely replaced by d*g*tal. Just like the repro industry.

    I thought Foma was, for instance.

    Ilford RC? Kentmere? No? (I wish I could insert Kodak and Agfa here.....)

    And why would Varycon make note of that if no DI was now the norm?

    Ole;

    In spite of Ilford's comments, MGIV tests positive for ID.

    Wish I could type....

    "None other DI RC papers?"

    Don't know how my fingers did that. Should have been something like "Are there any other none DI RC papers?"

    I don't know about DI, but Fotokemika Varycon's glossy seems about as glossy as other papers to me -- or at least, I didn't notice much difference in the few sheets I've printed. (I only bought a 25-pack of 8x10-inch sheets out of curiosity, and I don't have a sample in front of me.) It seemed hard to get a good rich black out of it, but maybe I just needed more practice with it.

    - those were made for rapid processing in
    high-volume labs,
    Freestyle carries one, a Graded RC. Even that requires
    a usual developer. Used for class instruction. I doubt you'll
    find one which responds to the usual developer activator,
    sodium carbonate.

    To test expose a piece of paper and develop it in
    a weak solution of that carbonate. Dan

    Dan;

    Many activators were Sodium Hydroxide or Sodium Phosphate to get the desired pH value that would unblock the developing agent. Many developing agents are blocked and require this stronger alkali for activation. Therefore, they fail the test with dilute carbonate. Strong carbonate, or one of the above that I mention would be better.

    Dear All,

    Whilst I would never refute Photo Engineer, in terms of his experience and knowledge and also would never, ever doubt his test results, no ILFORD Photo paper has developer incorporated.

    The early Ilfospeed paper was developer incorporated, something Ilford kept quite quiet at the time as they were selling Ilfospeed processing machines. It was processable in the earlier Ilfoprint machines but for best results required a modified Activator. I processed many thousands of prints usingactivator and Hypam in place of the stabiliser in the late 70's early 80's until Ilford changed the emulsion.

    Once the emulsion formula was changed the paper was no longer suitable and that was the end of my machine processing.
