line developer or graphic developer

hello people! could you suggest me a graphic developer or line developer???

i d like to process plus x super 8mm reversal and a big lab in europe told me that i should use a "line" developer also know as "graphic" developer...


many thanks

line developer thoughts

no formula on hand - but thoughts to guide you. Line developer was, in my mind a graphic arts developer for shops that used a lot of lith developer. Lith develope as in ph high nigh caustic and loads of hydroquinone. (different than present day lith printing technique) Lith developer gave infectous development, which would often swamp any fine line detail. So line developer was used when fine line detail needed to be preserved.

I would guess that if you take lith as a d-85 type formula, line developer would be milder in pH and less developing agent.

If you look at ot from the other end, say with D-19, a high contrast continuous tone developer, line would be likely higher in Ph with a more active developing agent pair.

Sorry, no definitive formulas, just thoughts to let you think on.

Line or graphic developers are very high contrast. If you are trying to make a positive image, use a wide latitude, continous tone developer for the first developer.

A couple of formulas for high contrast work.

Best,

--------------

Kodak D-8 film developer for very high contrast or low temperature processing

Cold Water 750 ml
Sodium Sulfite anhyd 90 g
Hydroquinone 45 g
Sodium Hydroxide 37.5 g
Potassium Bromide 30 g
Cold water to make 1L

Dilution: 2+1 (2 parts developer + 1 part water)

Starting point development time: 2 mins.

When mixing, due to the risk of heat reaction, dilute sodium hydroxide separately in a small amount of cold water then stir into mixture slowly in sequence.

------------------------------
Kodak D-11 high contrast developer

Water 38°C 500.0ml
Metol 1 g
Sodium sulfite anhyd 75 g
Hydroquinone 9 g
Sodium carbonate anhyd 25. g / 30 g mono
Potassium bromide 5 g
Water to 1 L

Average development time at 20°C in trays 4 minutes, in tanks 5 minutes.

To obtain slightly lower contrast, the stock solution can be diluted 1:1.

Solution shelf life in full bottle is 6 months, in partly filled bottle 1 month, in open tray 24 hours.

Capacity is 2700 cm² (5 rolls) of film per liter.

----------------------------
Ansco 70 Process film / reproduction

SOLUTION 1
Water 125 F 750.0 ml
Hydroquinone 25.0 grams
Potassium Metabisulfite 25.0 grams
Potassium Bromide 25.0 grams
water to 1.0 liter

SOLUTION 2
Cold water 1 L
*Sodium Hydroxide (Caustic Soda) . 36.0 grams
or
*Potassium Hydroxide (Caustic Potash) 50.0 grams

*Cold water should always be used when dissolving sodium or potassium hydroxide because considerable heat is evolved. If hot water is used, the solution will boil with violence and may cause serious burns if the alkali spatters on the hands or face.

Mix equal parts of Solutions 1 and 2 immediately before use.

2 min. to 3 min hard contrast

30-40 sec normal.

These developers tend to be all or nothing high contrast types. The more usual developer for reversal film is something like D-19:

Water (52C) 750 ml
Metol 2 g
Sodium sulfite (anh) 90 g
Hydroquinone 8 g
Sodium carbonate (mono) 52.5 g
Potassium bromide 5 g
WTM 1 l

Most reversal formulas add some sodium thiocyanate. Kodak D-94 adds 9.1 ml of a 51% solution. There was a recent thread that listed many reversal processes, and similar information is available in the Articles section. Any of those processes should work, although you may need to adjust the first developer time for the modern film. The Kodak website also has full information on processing PXR.

nworth,

I should have read the OP more closely! D-19 is probably a much better match to the need, as you suggest. I was looking for real "line" developers.

i d like to try lith developer......this is a good choice?
