Colour print film
AGFA PRINT CP30 is a multilayer colour print film designed for use in optical or contact printers for making co lour release prints from original colour negatives, duplicate negatives or internegatives. AGFA PRINT CP30 is characterized by its consistency, excellent sharpness, very fine grain and outstanding dy e stability. AGFA PRINT CP30 combines excellent detail reproduction in highlight areas with impressive deep neutral CP30 P R O D U C T I N F O
AGFA PRINT CP30
is the result of Controlled Light Diffusion (CLDTM) technology which has been developed by AGFA. The film consists of three emulsion layers, separated by light diffusion controlling gelatine interlayers and a special antihalation layer in between emulsion and base. The emulsion layers are sensitive to green, red and blue light and during processing a magenta, cyan and yellow dye is formed Coloured interlayers which reduce halation effects of light scattering in the emulsion and the special antihalation interlayer between base and emulsion have replaced the black rem-jet backing layers of echnology has made it possible to design a print film with coloured interlayers that absorb unused light inate halation effects more effectively than the conventional rem-jet backing layer. ulsion side is coated with a protective layer, containing lubricants, in order to provide protection from In AGFA PRINT CP30
, a new generation of blue sensitive emulsions has been introduced, resulting gher speed (2-3 trimmer points), a higher contrast and improved latent image regression characteristics. eed of the red and green sensitive layers are maintained on the same level as AGFA PRINT CP20. The itometric curves of the three light sensitive layers have been optimized to give a perfect balance over a wide tonal range, more saturated colours and deeper blacks without any loss of detail. When compared to AGFA PRINT CP20, one will be impressed by the improved blacks when screening AGFA PRINT CP30. This level is among the best that can actually be reached with standard motion picture printfilm stock, AGFA PRINT CP30
is coated on a 120 micron permanent antistatic GEVAR base, eliminating the attraction of dust and dirt during multiple projection runs. An environmental friendly conductive polymer (a proprietary AGFA concept) surviving chemical processing is introduced. The scratching resistance of the backing layer during processing is improved, thanks to the introduction of a processing surviving lubricant. The other advantages (e.g. tear strength, durability, dimensional stability) of GEVAR polyester safety base are dealt with in the publication “Polyester, the alternative film base with superior quality”, which can be obtained on request from your local AGFA representative. ottom CLD layer between emulsion and base contains Polyester Protecting Agents which protect the the subsequent laser subtitling process. In order to reach the optimum laser subtitling qua- olyester film needs to be processed keeping the chloride content in the film on the lowest possible level. AGFA PRINT CP30
is a fast developing emulsion, designed for use in all variants of the ECP-2 , including the latest ECP-2E version without First Fix and without silver-redevelopment. It
tains its gamma balance even in deviating developing conditions and is compatible with all commonly bleach systems. Since there is no carbon black antihalation backing layer to be removed, AGFA PRINT 0 offers the potential for eliminating the pre-bath, the brushing and rinsing phases. This will result in a cient processing, a significant reduction of water consumption and a lower chemical load in the processing effluent. Since dry film enters the developer solution directly, some minor changes to the developing time, replenishment rate and composition of the replenishment solution for the developer may be advised e.g. increase the developing time by 5 seconds, increase the replenishment rate by 5% to 10%, dilute the replenishment solution by adding an additional amount of water (5% to 10%). However, industrial application in numerous laboratories has proven that application of the standard settings for developing time, replenishment rate and - composition leads to good results as well. When compared to AGFA PRINT CP20, the water load of AGFA PRINT CP30 during processing has been d by 10%, which allows faster drying and less energy consumption in the drying cabinet. ntihalation dyes and/or sharpening dyes, used in AGFA PRINT CP30, are decolourized and/or re- uring processing. Although most of latter dyes are diffusing out of the printfilm during developing, plete removal of these dyes may also be influenced by the type of bleach that is applied. Since it is CP30 P R O D U C T I N F O
on practice for film manufacturers to design printfilm for use in an accelerator / persulfate bleaching m, the use of alternative bleaching solutions may lead to a slightly different value of the minimum er this colour imbalance, which may appear in evaluating control check wedges, is not noticed on the screen during projection of the release print. Since in case of the absence of the pre-bath, most of the water-soluble dyes are diffusing out of the printfilm during developing and will charge the developer, it is advised to keep the developing solution as clean as possible by means of efficient filtration and / or the use of the appropriate ion-exchange or adsorption resins. For further assistance, contact your local AGFA representative or AGFA headquarters.
In comparison with an exposure time of 1/100 sec., a certain loss of speed may be noticed when printed at This will require a printer setting adjustment: Since the final sharpness of any film depends upon every step in the exposure and processing chain (film ers, processing, projector lenses etc.), only the intrinsic and specific sharpness of the AGFA PRINT n be measured and charted as a reference. In the following graph, the Spatial Frequency refers to the ber of line pairs (sine wave cycles) per millimeter film length that can be reproduced. The Response indi cates the ratio of the modulation of the developed image to the modulation of the exposure pattern. Of-cour se the flatter the curve and the higher the response number, the sharper the film. use of a 10-Watt lamp or sodium vapour lamp with a Wratten #8 Safelight filter is recommended. ver, the maximum length of exposure to the safelight should be determined by darkroom testing and if 2
ry, the intensity must be reduced to an acceptable level with ND filters. Relative humidity: 50% +/- 5% at 20°C. PRINT CP30 offers film laboratories excellent colour timing and printing flexibility. It is balanced for sure to tungsten light with a colour temperature of 3200 K. dditive printing starting from duplicate negatives and original negatives, a typical printer setup is as 1000-Watt lamp at 70V with Wratten #2B and heat absorbing filter, running at 55 m (180 ft) / min. given settings may change in function of voltage variations. e figures apply to optical printers. However, due to a higher proportion of optical glass creating the of a far red absorbing filter, the red light exposure should be increased. CP30 P R O D U C T I N F O
quired, AGFA PRINT CP30, can be exposed in a subtractive printer also using the above Wratten #2B r correction filters can be used to modulate the light to the right balance. A positive variable area soundtrack can be printed on AGFA PRINT CP30 from optical recording films such as ST8D, ST9, or other brands of sound recording films. Excellent sound results will be obtained. The analogue soundtrack is formed by exposing mostly only the two top layers of the colour printfilm. This is achieved by selective exposure of the film with yellow light (silver soundtracks), greenish light (high magenta soundtracks) or red light (cyan dye only soundtracks) (*). AGFA PRINT CP30 has shown excellent results
when making Cyan Dye tr
acks where no silver-redevelopment is necessary anymore. For the digital
tracks – Dolby Digital SR.D, DTS and Sony SDDS, specific filterpacks and aimdensities are applicable. ata concerning filterpacks and aimdensities are available from your local AGFA representative or at sim ple request at AGFA headquarters. The exact working density values of the soundtrack negative and the print must be determined by means of app ropriate cross-modulation testing procedures. Also cons ult the technical data sheets of AGFA SOUND ST8D and ST9 optical sound recording films. oloured light is achieved by inserting the proper filter in the lightpath of the soundhead: - For Yellow light: insert a minus blue filter (AGFA L519 or Wratten #12) + a UV-filter, likeWratten #2B.
- For Greenish light: insert a high magenta filter (AGFA G0004 or Wratten #12 + CC Cyan 90 to 120 - For Red light (Cyan Dye tracks): insert a red filter (AGFA L622 or Wratten #29) In theory, the print is neutral grey if these values are applied. Due to the varying parameters of perception, in particular evaluation conditions and personal preference, these values may differ in practice. - r aw stock
