What Doctor-Blade Challenges Impact Wide-Web Cylinder Metering? Part 3

For gravure printing and coating applications, doctor-blade control needs to be both fast and foolproof with no guesswork, mechanical problems or startup waste that is attributable to doctor blade performance. While this statement is true for any gravure press, it is particularly important for wide-web applications that can have doctor blades with lengths greater than 100 in. When doctor blades are that long, setting them correctly and consistently to achieve effective metering can be more difficult because slight variations will be compounded over the length of the blade.For gravure printing and coating applications, doctor-blade control needs to be both fast and foolproof with no guesswork, mechanical problems or startup waste that is attributable to doctor blade performance.
