MACO MULTIBROM F (111 )
MACO MULTIBROM N (112)
MACO MULTIBROM WA
A short summary of attributes of these black & white photographic
papers:
- MULTIBROM De Luxe offers a combination of modern emulsion-technology
with classic baryta-fiberbase (VC-FB).
- MACO expo Display offers a synthesis of the MULTIBROM-emulsion together
with an especially stable and ageing-resistant polyester base. Due to this
basematerial MACO expo Display offers - for the first time ever - an alternative
to manual processing of baryta papers - processing in developing machines
makes efficient production possible, while maintaining archival properties.

| MACO MULTIBROM N, |
|
| MACO MULTIBROM WA: |

MACO expo Display:
|
* unique high gloss with RC-dryers and air drying
(not suited for baryta dryers) |
4. Image tone of the photographic emulsion:
MULTIBROM papers and expo Display have an emulsion with neutral blacks.
Can be manipulated by use of different developers.
For example:
MACO ecoprint
LP-BROM 1
Calbe MH 28
LP-BROM 3 |
- cold image tone
- warm image tone
- very warm image tone
- cold image tone |

Note: The dye used for the cream tinted base at MACO MULTIBROM WA is
to some degree water soluble. Long washing times more than 30 minutes ma
weaken the intensi of the cream tint.

Note: With MULTIBROM WA, due to lower reflective power of cream tinted
base paper ISO-speed values are
about one f-sto lower.
7. Filtervalues/enlargers with colorheads: MACO
MULTBROM and expo Display papers can either be exposed by using filtersets
(e.g. LABOR PARTNER VC-Filter, ORIENTAL Acrylic VC-Filter or ILFORD Multigrade
Filter, table above) or with enlargers with VC-head.
With colorenlargers use the following values as a starting point: (check
whether your enlarger has DD - or CC-filtervalues)

Depending on age of lamp, type of filter and enlarger deviations to a.m.
values is possible.
8. Maximum density:
The glossy surface achieves the highest values (MULTIBROM F and expo
Display). Matte Surfaces achieve in comparison lower values.
Following (approx.-) values have been achieved with a negative (Gamma
0,60) in combination with the paper developer LP-BROM 1.

11. Toning:
MACO MULTIBROM and expo Display photographic papers can be toned in
almost all available toners.
Following some application examples:
Deep, brown blacks:
|
A: Treatment in PEERLESS watercolors.
B: Toning in LABOR PARTNER LP-SEPIA. |
| Light brown/ yellowish |
A: Toning in LABOR PARTNER LP-SEPIA with adding vinegar. |
| Bluetoning: |
A: Toning in LABOR PARTNER LP-AZUR. |
Toning with LP-SELENIA
|
A: Increasement of max. density.
B: Improvement of archival quality (image silver) C: Change of image
tone |
For gelatine toning, whether partially, or full image, using PEERLESS-watercolors(
U.S.A.) has been proven for more than a century.
12. Retouching:
For MACO MULTIBROM and expo Display papers PEERLESS-watercolors "DRY
SPOT SET" have been proven. The colors may be adjusted to the image tone
and leave no marks on the surface.
13. Darkroom safety light:
Protective filter red or amber. Max. 15 Watts, minimum distance Lamp
- tray 120 cm (a fogging test may be recommendable).
14. Informations for processing:
MACO expo Display:
Suitable are all aviailable high quality photographic chemicals. Best
results can be achieved with MACO or LABOR PARTNER photographic chemistry,
for tray processing as well as for machine processing: Due to the fact
that expo Display is equipped with a translucent base, one can produce
normal prints as well as
images for backlighting purposes (displays etc.). In order to render
optimum image reproduction, please keep in mind that depending on application
exposure time has to be adapted.
Note:
The unique image effect of expo display is due to the special base
being extremely stable and smooth , therefore being responsible for the
unique glossy finish.
Correct processing provided, expo display will render longterm-stable
black&white prints of unique attractiveness.
Tray processing:
To get prints with a flawless surface please take special care. Prints
to be processed should be handled on the very edges only - place prints
into solutions emulsion side up in order to avoid scratches.
Machine processing:
For flawless glossy finish of the prints, condition of the machine
is decisive. Check whether all rollers are clean - e.g. no crystallisation
of chemicals. For maximum blacks - due to the high silver content of expo
display- check condition of chemistry, if in doubt regenerate or renew
chemistry. For machine processing MACO recommends the fully compatible
LABOR PARTNER LP-SPEED 2000 chemistry (available with and without regeneration).
MACO MULTIBROM F, N + WA:
All MULTIBROM papers are suited for tray processing with all available
quality photochemistry.
15. Storage:
Original MACO packages, once opened, should be stored in a cool and
dry place. Packages feature easy opening on opposite side of label, punches
under the lid allow for easy closing.
