PORTRAIT
PAPER
P R O F E S S I O N A L
AGFACOLOR PROFESSIONAL PORTRAIT PAPER is a pro-
fessional enlarging material with a polyethylene/resin-coated
base. It is designed for the production of prints from colour
negatives. The paper is optimized for skin tone reproduction.
Additionally, due to its lower contrast compared to standard
papers, this paper is well suited for subjects that require addi-
tional definition in highlights and shadows.
The latest emulsion technology, optimized for portrait use and
perfectly engineered coating provide for a colour paper with
exceptionally high-grade photographic characteristics, and of
great uniformity and stability. It therefore satisfies all the quality
requirements of portrait photographers and portrait labs.
AGFACOLOR PROFESSIONAL PORTRAIT PAPER
" features excellent reproduction of different skin tones,
" produces exceptional neutrality, pure whites and neutral
blacks. Colours and skin tones are rendered correctly,
" shows excellent reciprocity characteristics, i.e. filter values,
speed and contrast remain virtually constant with the
commonly used exposure times,
" has high latent image stability,
" has maximum stability with all the standard process variants
and process deviations, and so ensures high productivity,
" is backed by maximum consistency of production to ISO
Standard 9002,
" produces prints with high dye stability.

Storage at deep freeze temperatures of  20 °C /  4 °F delays
the aging process of the paper considerably, and so extends
the storage life.

For technical reasons some paper rolls have to be supplied
with splices. The maximum number of splices we permit (in
accordance with ISO Standard 1009) are given below for each
roll length:

be stamped, written or printed on.
Packing
The original packaging protects the paper from the effects of
light and short exposure to moisture or fumes.
Emulsion structure
Rolls up to a width of 12" (30.5 cm) are packed in double-layer
bags. A carton contains from two to eight rolls, depending on

Emulsion number
A 14-digit product coding is printed on the labels. It begins with
the 5-digit ABC code, followed by the emulsion number and
three letters serving internal control purposes.
The complete line of coding should always be given in inquiries
