Crane is best known for its stationery products, including letter/envelope combinations and notecards. In response to the growth in inkjet printing, the company developed Museo fine-art digital printing papers. The latest of these is Museo Portfolio Rag. This heavy 100 percent cotton rag paper has a smooth surface and, unlike some lesser papers, does not contain optical brighteners, additives that brighten whites under certain lighting but that may also accelerate fading. As a result it has a warmer-looking tone. In addition to standard-sized and metric-sized sheets (8.5x11 to 35x47 inches, plus A4 and A3), the stiff, hefty Museo Portfolio Rag is available in rolls. Roll widths include 17, 24, 36, 44, and 50 inches. Other Museo papers we like include a new water-resistant Canvas paper for pigment inks that's available in both glossy and matte surfaces.
