Heat Transfer Printing Base Paper

Transfer printingTransfer printing is the term used to describe any process involving the transfer of a coloured design from a print on paper to a textile or polymeric film like substrate.The method most widely used is a vapour transfer printing,whichdepends for its success on the volatility of the dye used and on the preferential absorption of the dye vapour by the textile material with which it is in contact.The method is often termed "Heat Transfer Printing" because of the high temperatures used (greater than 180°c) to ensure an adequate supply of dye vapour.The procedure involved in vapour transfer printing comprises:-(1) Preparation of the paper.(2) Application to the paper of specially prepared inks comprising a number of colours to make up aknown design.(3) Transfer of this design,ideally with complete transfer of the dyes,to a textile material by dye volatilization,as rapidly as possible,at optimum temperatures.There are a number of technical considerations which need to be taken into account in the above process.Briefly:-Transfer Printing PaperThis is must bestrong enough to prevent tearing and retain adequate strength when subjected to the temperatures used in the transfer stage. The specification of the paper depends on the printing method to be used but in all cases an evenly formed paper free from surface dust and defects is required. In addition the reqirements of the printed paper at the transfer stage are:-(a). Good release of dye vapour from the ink layer.(b). Good strength retention on heating up to 220°c.(c).Low permeability to the dye vapour.Printing of the Transfer PaperThe printing on paper of heat transferable designs can be achieved by any of the commercial processes employedin the printing industry,namely:- Gravure Flexographic Lithographic Screen---flat and rotaryTransfer Printing InksThe dyes used in the formulation of transfer printing inks must be volatile at the temperature employed in the transfer process i.e. they must be of relatively low molecular weight and notcontain any water solubilising ionic groups which can restrict or prevent volatilization.will be always following the step of the heat transfer printing,we offer the best quality base paper producedwith 100% pure wood pulp, GrandCorp has proven to be the industry's best in quality and service, our mission is to produce heat transfer base papers to exactly your specificaion in the quantity you need.We are the only China heat transfer base paper producer in wide width paper-up to 3750mm,We welcome you and your team to visit our plant.Specification:-1).
