The Diddl relief sheets represent a particularly sought-after category among the special sheets in the collection. Embossing consists of raising certain areas of the paper to form a relief pattern, creating a unique tactile dimension that distinguishes these sheets from classic versions.
This cold embossing technique was applied to Diddl motifs to create depth and texture effects on the paper. Embossing allows for a recessed finish, while debossing offers a relief result on the paper, giving the sheets a premium quality highly appreciated by collectors.
With 98 references recorded, relief sheets constitute a specialized sub-category that testifies to the brand's constant innovation in the field of stationery. These sheets, often combined with other special effects such as fragrances or particular colors, were particularly coveted during exchanges in schoolyards.
