Principlesofcoldstamping
ColdstampingistouseaflexibleplatetopartiallyorfullyprinttheUVglueontothepapertape,andcombineitwiththetransferfilm,andthenirradiatetheUVlamp,thegluewillinstantlysolidifyAfterpeeling,thelaserlayeronthetransferfilmwillbetransferredtothepapertapeaccordingtothepatternontheprintingplate,formingagorgeouspackagingeffect.Itiscalledcoldstamping(coldtransfer)becauseitdoesnotrequireheating,whichisdifferentfromtraditionalhotstamping.
Advantages:Comparedwithtraditionalhotstampingtechnology,coldstampingtechnologyhasobviousadvantages,whicharemainlyreflectedinthefollowingaspects.(1)Lowcostofplatemaking.Coldstampingdoesnotneedtoproduceexpensivemetalstampingplateslikehotstamping,anditalsoavoidsenvironmentalpollutioncausedbytheprocessofstampingplates.(2)Thehotstampingprecisionishigh.Theresolutionofcoldhotstampingisrelativelyhigh(basicallyitcanreachtheprintingresolution),whetheritishotstampingsmalldotsandlines,orachievingaholloweffect,itsexpressivepowerisverygood.(3)Theareaofhotstampingpicturesandtextsislarger.HotstampingisgenerallyonlyusedforhotstampingofgraphicsandtextswithasmallareasuchastrademarksandLOGOs,whilecoldfoilhasalargerwidth,evencomparabletothatofaprintingmachine,soitismoresuitableforhotstampingoflarge-areagraphicsandtexts..(4)Awiderrangeofapplicablesubstrates.Coldstampingcanrealizethetransferofcoldstampingfoilbytheactionofadhesiveandpressureatroomtemperature.Itdoesnotrequirespecialadjustmentandcontrolofstampingtemperaturelikehotstamping.Itisnotonlysuitableforstampingcommonsubstratessuchaspaperandcardboard,butalsoforhotstamping.Deformablethinfilmmaterialscanalsobeapplied.(5)Itiseasiertoachievehotstampingandthenprinting.Intheprocessoffirsthotstamping,coldstampinghaslowdifficulty,highefficiencyandlowscraprate.(6)In-lineproductioncanberealized,withfasterspeedandhigherefficiency
