Framing should be museum quality.  Only acid free mats should touch the prints. Any others will slowly destroy the paper.  Prints should be suspended by acid free paper tabs that will tear before the paper of the print itself when put under any stress.  They should be under glass, ideally without the glass touching the print surface. Usually Lagana's prints look best in light colored mats.  Sometimes an accent adds richness.  More often just one simple mat is best.  Purists do not cut the margin.  However,  Lagana often leaves extra wide margins, so some trimming is possible.   Allow for an equi-distant margin of 1/2"  to 1"  showing around the print so that the signature is displayed, and leave as much paper as possible underneath the mat for protection of the print itself.  Prints can be laminated.  If you wish a perfectly wrinkle free surface on the big prints, it may be necessary. However choose a professional framer and use a reversable adhesive.

Japanese mulberry papers have flecks and other irregularities of hand made papers.  Over time some of these papers show light  oxidation spots from the impurities in the water used to make the paper.  These spots  blend with the paper.  If the print is kept in air conditioning, these oxidations willl not occur or increase.
