Hello.
Are 131 and 132 fomatone (warm) fiber papers (glossy / semi-matt) the same emulsion? I just read 132 has a creamier base than 131...
And, are/is the same emulsion/s available in any resin coated version/s by Foma?
Thanks!

Foma is using the same warm tone emulsion on all 'MG Classic' papers (131, 132, 133, 532 and the unfortunately discontinued 542). According to their data sheet, they made some changes to the emulsion starting with lot number 0680, which are relevant for lith processing.

The papers 131, 132 and 133 are using the same warm white paper base, but have different surfaces. I have only been using the 131 and 133 papers (not 132) and the paper base might appear slightly different due to the different surface structures, but it is the same paper. The 532 and 542 papers are completely different with a fibre based, but not baryta coated base.

The only RC papers available from Foma, the fixed gradation 'Fomaspeed' and the variable gradation 'Fomaspeed Variant') are using different neutral tone emulsions. Foma does not manufacture any warm tone RC coated papers.

They do have 331 and 332, which is rc warmtone.

Such a generic classification is not particularly useful if someone asks about the difference between two Foma papers.
Just by looking at the classification table, it might seem as if e.g. the 132 and 532 papers are very similar, just having different 'base types'. In reality, both the base colour and the surface structure are completely different.

Sorry if I gave the impression this table would answer all the questions, it was simply meant as an additional info to decipher those numbers.

I absolutely agree the numbers should not be interpreted too strictly, e.g. one should not be fooled into thinking that surface "2" will always represent exactly the same type of surface structure across the different paper product lines (RC/FB, WT/NT ...)
