If yes, how so?is there any PDF or tutorial about that?<br /> -<br /> <br /> just tell me what to do, link me some tutorials or pdf and please help me out. because starer didint come with anything and I cannot read Chinese <img title="Cry :cry:" src="http://www.apug.org/forum/styles/apug/smilies/cry.png" alt=":cry:" /><br /> <br /> thanks</p>

Hi, without having double checked, the part numbers look like Kodak LORR replenisher and LORR starter.

 

The mix instructions should be on the starter label if you can get someone to translate for you. Failing that, Kodak pob CIS-49 should have

the info; see table 4.

 

The way I read this (even though part #s don't seem to line up) is: 763 ml replenisher + 207 ml water + 30 ml starter = 1 liter of working tank

solution. Again, I have not double checked; hopefully someone will verify?

[Bill C]

Regarding your other questions: this mix - replenisher, water, and starter - will give the "working tank" that you use to develop film. After

devoping, you do what you want with it. If your system allowed, you could add the appropriate (small) amount of replenisher and develop

more film, then keep repeating this sequence. Unfortunately, your rotary (Jobo) process aerates the developer so much that replenishment

is not recommended. So it seems that "single use" is the only option with Jobo.

<p>Thanks so much Bill, the numbers you gave looks like really close with the label. I see those numbers!<br /> 860 ml something ( probably reple) + 18ml starter + 122 water.<br />-<br /> If I'm going to use that much of Replenisher and just a little bit of stater, I guess I dont need that much of developer starter, am I right? I have 1.2 liters of it and if 1 liters of active solution only requires 18 ml, that means I can make close to 83 liters. <br />-<br /> After creating my first active solution, I will have about 4.2 liters of replenisher left and 1.18 liters of developer starter. I wonder why the smallest size for this product is 1.2 liters. <br /> Do you know how much replenisher to add after developing a roll of film? is there a pdf anywhere?<br /><br /><br />Why kodak makes everything this hard, is it really necessary?</p>

<p>The Kodak Flexicolor Developer Replenisher C-41 LORR is a solution used in machine film processors such as high volume photo labs and mini-labs. It will be OK for your use. <br>

The LORR formula develops C-41 film, time of development is 3 minutes 15 seconds at a temperature of 100⁰ F (37.8⁰ C). If properly replenished the life of a working tank solution is indefinite. The replenishment rate is 19ml per roll of 35mm 24 exposure. This formula has a lower replenishment rate than its predecessor thus the term LOOR for lowered replenishment rate. <br>

The Developer Stater is a one-time add to a tank of unused Flexcolor LORR developer. The bottle contains 1 quart (32 oz.) of fluid. The entire bottle makes 8.3 gallons of working solution Flexcolor Developer. Breaking this down, 1 ounce starter to 32 ounces Flexcolor LORR.<br>

<br>

Note: The C-41 developer is depleted somewhat with each roll processed. The replenisher added at a rate of 19ml per roll of 35mm 24 exposures restores the developer to full strength. All developers contain a restrainer, in this case bromine. If the restrainer is not present, the developer will develop unexposed areas. As film normally develop byproducts of development are leached from the film. One of these is bromine. Thus the developer gains brome restrainer with each roll processed. The C-41 LORR Replenisher Formula contains no bromine. We add bromine using the starter as a one-time add to make a seasoned tank formula. </p>

LORR."

 

Thanks Alan. Your starter addition numbers are close to the ones I came up with.

 

Kadir, I think the starter addition you are speaking of is too low; that addition may be for the "conventional" replenisher, not for LORR. I did

verify your replenisher part #, and it IS the LORR replenisher. As Alan indicates, the LORR version uses a lower replenisher rate which

implies that it contains a lower concentration of byproducts (the restrainers), and therefore it needs more added via the starter solution.

Thus I conclude that your number for starter - 18 ml - is most likely for the conventional replenisher. Whereas you have the LORR

replenisher, so need more starter. But of course, I could be wrong.

 

Ps, it occurs to me that if you posted a photo of the label there are likely people here who could translate.

<p>Easy for production labs, hard for home use.</p>

[Bill C]

"Easy for production labs, hard for home use."

 

Actually, also hard for production labs, but with enough processing volume the chemical cost savings made it worthwhile. (I'm not sure if it

would anymore; the customer volume may not ever show up.)

<p>I know this is not exactly the thread to ask this question, but since I'm new to the forum I thought I might have a better shot at finding help here than posting a new question. So here it goes:<br>

We have a colex ra4 processor which we've been using (at school) for the past 10 years to teach color printing. We use Kodak Ektacolor PRIME SP Developer Replenisher SP Lorr, which we always mix (when he first fill the tank) with the Kodak Ektacolor PRIME SP Developer starter SP Lorr. This year, we don't have starter and I'm hesitant about filling the developer tank without it. Can anyone give any suggestion on what I should do? Thanks</p>

[Bill C]

Hi, if I were in your shoes, I'd call your supplier and see if they can get you some starter.

 

Do you have some "process control strips" that you periodically process, then read with a densitometer? If you can't get starter quick

enough, and you have some "dummy" paper (meaning no good, perhaps accidentally fogged) you could expose some of this and process it.

By trial and error, using the control strips to measure the result, you could approximate the effect of the starter.

 

If you had to, and if none of the work is critical, you could try just using the (diluted) replenisher. It will start out as overly "active," perhaps you

won't be able to keep a white paper base, but eventually, with use, it will reach the normal condition. I personally wouldn't want to do this,

fwiw.

<blockquote>

</p>

<p>As I understand it, not having actually done it, you put the bottles in, and the machine, under computer control, sucks the right amount from each one. <br>

<br>

Well, as above, that might be after the appropriate starter mix, if the computer doesn't do that one. </p>

[sofia_silva]

<p>Thanks for the response Bill, we're in Portugal and the school sometimes messes up the orders, that's why the starter is missing. I experimented with the diluted replenisher (in manual processing) and saw the differences, that's why I am so hesistant, but if you say with use it "normalizes" I might just go ahead and start processing. <br>

I've read that using the replenisher without the starter also "comsumes/exhausts" the developer more quickly than desirable. Can you confirm it?</p>

[Bill C]

"I've read that using the replenisher without the starter also "comsumes/exhausts" the developer more quickly than desirable. Can you

confirm it?"

 

Hi, well yes, the developer will initially be "used up" quicker, then this rate of change slows down as it approaches the normal equilibrium.

Stating this differently, a replenished system, at a given replenishment rate, will eventually stabilize at some level of developer "activity."

And the farther away from this point that it starts, the faster the rate of change. But this is not a bad thing - it gets you to an in-spec range

quicker.

 

I think that your big problem with this, aside from a possible color tinge on the "white" areas, is that a student trying to color balance a print

may have to also fight with a changing process. Especially if they have a delay between tests when other students are processing.

 

My recommendation would still be to see if you can get the starter. If this cannot be readily done, my question about "control strips" comes

in. If you have these, plus a densitometer to read them, you can basically measure how far away from normal you are. Then you could

bring it closer to normal by processing some test runs of fogged paper, using control strips to check your progress.
