Abstract
The present invention relates to a method for enhancing leather edge imprinting. More particularly, the present invention relates to transferring the print from the transparent paper to the edges of a material. Further, the present invention enables in tailoring the designs or written logos on the edge surface for desired applications. The method [100] for imprinting a pattern on edges of a leather substrate comprises of steps with pattern imprinted on the edge across the perimeter of the leather substrate. The pattern comprises one or more customized colors, text, names, company brands, slogans, patterns, images, graphics, photographs, logos, advertisements, or a combination thereof. Advantageously, the present invention effectively saves time and material wastage.
Claims15
A method [100] for imprinting a pattern on edges of a leather substrate, comprising the steps of:
- burnishing [101] edges of the leather substrate;
- application [102] of an adhesion promoter on the edges of the leather substrate, followed by drying for a pre-defined period of time;
- application [103] of the adhesion promoter on a transfer film comprising a pattern;
- transferring [104] of the pattern from the transfer film to the edge of the leather substrate on application of pressure and temperature, followed by drying for a pre-defined period of time;
- removal [105] of the transfer film;
- application [106] of a first chemical coat on the edge of the leather substrate and drying for a predefined period of time;
- and
- application [107] of a second chemical coat on the first chemical coat and drying for a pre-defined period of time,
- wherein the first chemical coat comprises of a dispersion of fumed silica (40% w/v) in aqueous Polyurethane solution 60% w/v.
