Hitch Standard

Hitch standardization is a process by which two or more instruments of similar design can be made to read the same color values on a group of specimens. This process is very useful in expanding the communications of color around the world or between vendor and customer.

The process of hitch standardization also known as transfer standardization involves assigning one instrument to be the reference, or master, unit and mathematically adjusting the secondary, or slave, unit(s) to read the ‘same’ values. In this way, two or more instruments can be hitched together. Hitching a secondary unit to a reference instrument requires that a specimen be read on both units and the values compared and adjusted accordingly. This specimen, known as the hitch standard, is first read on the reference instrument and its values recorded as spectral data or colorimetric (tristimulus) data. The hitch standard is then physically moved to the secondary instrument where it is reread and the values from the reference unit are input into the secondary instrument’s processor.

· A long press on the standard name, will provide a selection for Hitch standardization.

A workspace is a collection of user preferred parameters (Color Scales, Indices, Tolerances, etc.) as a template. When a user exits Easy Match Essentials and returns, the last used Workspace will be loaded if the user has selected that option in Jobs: Preferences.

Jobs vs. workspace: A job consists of standard and samples measured into a specific workspace. There can be only one job open at a time. A new job will use the current loaded workspace settings. The user can change the settings and these changes are applied into the current job. The last loaded workspace settings are applied automatically when the user creates a new job. The main tool bar provides the options to create a new job, open an existing job and save a job.

Workspace: Views

Views are used to select the screens for viewing results. Simply check on the box of the screen needed. Press Apply to save one or all of the screens. The default screen is the Color Data Table. To navigate between screens once the selections have been applied, use the View Flippers on the left and right of the screen.

Workspace: Load Workspace

Press LOAD WORKSPACE to recall any previously saved workspace from the database. The newly loaded workspace settings will be applied to the job and all existing measurements within the job will be adjusted accordingly.

NOTE: When a user exits Easy Match Essentials and returns, the last used Workspace will be loaded when the option LOAD LAST WORKSPACE AT STARTUP is selected in JOB : PREFERENCES dialog.

Workspace: Save Workspace

The current workspace parameters are saved into a database with a user specified name. Saved workspaces can be moved up to the SWITCH area if desired by dragging and dropping. If no workspaces have been saved, then only default will be present.
