order and quality required. Jacobi adds that future developments in the
process will involve artificial intelligence to improve the quality of the recipes produced further, ensuring a perfect match in any location. BYK-Gardner has introduced a new benchtop
spectrophotometer — the Color2view — that uses circumferential illumination at 45° with 0° viewing to measure colour as it it seen. The circumferential illumination from ten directions is said to ensure repeatable measurement results on textured surfaces. Simultaneously with colour, 20° and 60° gloss are measured to clearly differentiate medium gloss and high gloss samples.

allow customers to manage product data developed in the laboratory with production and Enterprise Resource Planning (ERP), Manufacturing Execution System (MES) and Laboratory Information Systems (LIMS). Developed as a cloud-based module for the Colibri platform, the matchmycolor Hub centralises and manages master data by allowing the creation of colour products on request from a centralised system, as well as preparation of digitalised collec- tions and shades. It also allows the development and design of master recipes by the laboratory for production, and the correction of recipes from production triggered by production orders. The matchmycolor Hub has standardised
Application Programming Interfaces (API), which allow communication with third party centralised software solutions via custom specific connectors. This makes it suitable for a wide range of industrial applications, including processes where colour plays an important part in the appearance of the final product. As an example, Jacobi describes the automatic
correction of Colibri recipes in production triggered by SAP for a large multinational company that was interested in streaming and automating the colour correction step directly in production. It wanted to start the order process from SAP and send this to the Colibri platform to commence the quality control and correction of the product, if required. To accommodate the request, a workflow was implemented. A production order (the quantity and recipe to be produced) is sent from SAP to a production workflow component to start the process. A request is sent to the matchmycolor Hub for all colorimetric data required to fulfil the order, which is returned and the quality control job automatically started. If a correction is required, a request is sent to the Colibri platform and the corrected recipe automatically dosed. The final amounts dosed are then returned to SAP. The customer can also perform multiple corrections until the final product meets the

Assessing stability The Color2view also has a fluorimeter integrated to predict lightfastness by quantifying fluorescence – the calculated colour change after fluorescence degradation is displayed with easy-to-understand CIELAB and DE data. The combination of spectro- photometer and fluorimeter is claimed to open new perspectives for controlling colour quality and guaranteeing long-term colour stability. The Color2view Pro version also offers a Jetness
Mode, which is specially designed to measure deep and deepest black with highest accuracy. It features good technical performance, which is also assured for a low reflectance range (R) of less than 0.1%. According to BYK-Gardner, the system is
easy-to-operate, with intuitive navigation. The compact and lightweight instrument can be easily rotated to adapt to the orientation - top or front port - required or to the sample size and shape. Operation via the colour touchscreen is icon-based while an integrated camera presents a live preview of the measurement spot to avoid false readings. The BYK LED technology provides good
short-term, long-term and temperature stable performance while the extra-large measurement spot with homogenous illumination is said to guarantee repeatable and representative readings. Digital standards can be exchanged between benchtop and portable colour instruments without any extra-profiling. Due to good intra-instrument agreement between Color2view and Spectro2gu- ide units, the company claims seamless use of digital standards is possible.
