This can help shorten the time-to-launch of new product ranges, allowing fast and reliable checks prior to initiating sample development and simplifying the overall decision-making process for brand owners and technical colorists.   As early adopters of our PCR Color Prediction Service, L’Oréal achieved consistent colors across various PCR grades in different countries, enabling them to launch with fewer color iterations and color trials, thereby reducing complexity and increasing speed.”

Such advice, for example how to set up blow molding machines, is not equipment specific and therefore ColorMatrix would always recommend using local or expert technicians in addition to following best practice points listed below; • Preforms should be conditioned for minimum 24 hours prior to blowing • Preforms should always be used in a FIFO manner (First In, First Out) • Octabins of preforms should be segregated and blown per resin type, i.e. not mixed with other resins • A preform traceability system should be in place such that any process upsets can be quickly followed up and corrected • Enhanced QC preform checking resources for bottle distribution, aesthetics and integrity should be on-hand during the performance optimization trials • Prior to any process optimization, the blowing machine performance should be verified as being within normal i.e. accepted standard ranges and all important components and control features are working satisfactorily. Maximum speed output should be attainable prior to any ‘recipe’ setting trials TECHNICAL BULLETIN The diagram below shows many of the variables that are typically present during stretch blow molding and this illustrates the complexity of the whole process.
