Arches
A pad of 12 hot pressed watercolor sheets, 9 x 12 inches and 140 lb (300 gsm), made from 100% cotton with gelatin sizing.
Best for: Watercolor painters who want smooth, hot pressed 100% cotton paper
The Arches Hot Press Watercolor Pad holds 12 sheets of 9 x 12 inch, 140 lb (300 gsm) watercolor paper made from 100% cotton. Hot pressed paper has a smooth surface, the texture most often chosen for fine detail.
Arches makes the paper on a cylinder mold that spreads the long cotton fibers evenly, which it says gives exceptional resistance to tearing and linting and lets the sheet slacken uniformly when wet. Its gelatin sizing keeps paint from penetrating the paper and, Arches says, increases the luster and transparency of colors. Arches has made paper since 1492.
Based on the manufacturer's Amazon listing.
Arches uses long cotton fibers in a natural white sheet.
A smooth surface, generally chosen for detail work and fine lines.
Arches says the process spreads fibers evenly for exceptional resistance to tearing and linting, and uniform behavior when wet.
The sizing keeps paint from sinking into the paper, which Arches says increases the luster and transparency of colors.
The natural white sheets are pH neutral with no optical brightening agents.
Each sheet removes easily from the glued edge.
Look elsewhere if: you want a smooth surface for practice. The Fabriano Studio Hot Press Pad has 50 hot press sheets.
