KENTMERE 
Kenthene 
For those who prefer the qualities of traditional graded papers on a resin coated base, Kenthene offers more than just an alternative. Kenthene is a high quality uersatile paper, with truly superior blacks. A significantly deeper richer black can be achieved compared with many alternatives and in a fraction of the time, due to fts high speed sensitive emulsion. 
Designed for fast processing with superior dimensional stability, Kenthene boasts a range of grades and surfaces second to none, including Satin, Stipple and Glossy finishes. Superior lustrous blacks of neutral image tone, brilliant base whites and excellent tonal rendition characterise Kenthene, the discerning alternative for those who prefer graded papers. 
Product Description 
Kenthene is a resin coated medium weight paper with a high speed graded emulsion. Available in contrast grades 0 - 4. 

Surfaces 

  • Glossy: This paper has built-in glaze to provide the maximum black density and overall print brilliance. Maximum gloss is achieved through hot air drying.
  • Satin: A semi-matt surface provides a quality enlarging paper with low reflectance properties which facilitates print retouchi rig.
  • Stipple: An embossed semi-lustre paper with a high density range.
Paper Structure 
Paper Base 
The paper is 190 g/m2 coated on both sides with 40 g/m2 of polyethylene giving a base weight of approximately 270 g/m2 and a thickness of approximately 245m. 

Coated emulsion layer 
The light-sensitive silver halide emulsion layer has a silver content of approximately 1 .6 g/m2. This is covered with a gelatine supercoat which protects the emulsion from stress fogging and physical damage and also contains a developing agent.

Maximum density 
Kenthene will achieve the following maximum densities: 
 
Glossy 2.20
Stipple 1.95
Satin 1 .90
(the Satin surface contains matting agents which reduce the maximum density achievable) 
All these figures represent an average of the achievable results. A small amount of production tolerance is included. Actual results achieved may differ depending on processing, paper age and storage conditions.

Results achieved using Kentmere VC Select Plus Developer at 1 + 12 at 20C as recommended under processing instructions. Other recommended developers and fixers (see Processing) should give comparable results. 

Safelighting 
Kenthene graded papers have conventional bromide emulsions, which can be used under standard safelights for non-VC type printing papers. Always keep safelight exposure to a minimum; returning unused paper to its original packaging. 
Safelight filters which are suitable for use with Kenthene graded paper are Kodak OA, OB, OC, or 1A, and Ilford 902. Fluorescent safelight tubes such as Encapsulite A 10/ND.4 are also suitable. 
Other safelights can be used, but tests should always be carried out first. 

Processing 
To maximise d. max, and tonal rendition, we recommend a high activity chemical system such as Kentmere VC Select Plus Developer and Fixer. The following developers will also give excellent results under either machine or dish development. In alphabetical order: Agfa Neutol, Champion B&W Multicontrast, Ilford Ilfospeed, Ilford 2.000, Kodak Polymax, and Tetenal Variospeed developers, together with their appropriate fixers. Equivalent products from other manufacturers should give similar results, as will most multicontrast developers. 
The following table shows recommended dish processing conditions for use with Kentmere VC Select Plus Developer and Fixer. If using another manufacturer's chemistry, refer to their instructions for recommended processing conditions, to achieve similar results. 
Kenthene graded papers are not suitable for use with activation chemistry.

Drying 
Kenthene graded paper can be dried using any standard resin coated paper drying methods, these include: 
Warm air drying up to temperatures of 
80C. 

  • Atmospheric drying, having removed excess surface water using a suitable print squeegee.
  • Warm air drying, as in purpose made print drying cabinets.
  • Infra-red dryers such as the Ilford Ilfolab 1 250 Dryer or similar.
Note:- Kenthene graded paper should NOT be used with a rotary glazing/drying drum or flat bed glazing/drying press.
