The usual use of particular abrasive paint, for example, in steel engraving leads to wear on the metering edge despite the use of previously used carbide cutters on the ink blades or ink blade sections, which means constant readjustment or replacement of the ink knife. With exchange exists so far the

Necessity of a very accurate fitting, d. H. Zeroing the individual zones, which is extremely time consuming and often not feasible by the customer.

By preferably a one-piece ink knife is used, which is different from the co-acting with him adjusting means, the adjusting elements are previously adjustable so that the zero position of the actuating means or their drives when changing blades does not have to be reset each time. In addition, this prevents wear on the possibly more expensive adjusting means themselves.

By the ink knife is separable from the adjusting means, the knife can be used at several of its edges as dosing.

A color gap receiving nip is preferably carried out with an oversize in its length, so that in the assembled ready colorimeter this non-end, ie with its dosing edge 27 opposite end, in the nip strikes.

With a single mounting device, several or all color knives for all ink boxes of the printing press of the same type and the same design can be adjusted, possibly for other machines with the same color box type.

In a further development, the colorimeter measures the area outside the setting means, i. H. the nominal diameter, surmounted and rests on non-adjustable guide rails on both sides, a lateral seal is created in a simple manner.

In an advantageous development, the adjusting means have a possible

Gesamtverstellweg, which is significantly greater than that strictly necessary for the operational opening and closing of the gap. With appropriate Zero adjustment in the context of the use of a turned, regrinded or new ink knife, the not used for the adjustment in the printing operation to

Readjusting the zero position, z. B. necessary because of wear of the ink knife edge, can be used. Thus, an adjustment of the zero positions can be done directly with the actuators of the actuating means. Only with complete utilization of the total adjustment range is the respective color knife to turn or to turn, or to exchange for a new knife or a newly ground knife. The original zero position of the actuating means is then approach this again. By simply taking out together with the knife holder and accurately re-inserted color meter is a cleaning of the color meter outside the

Color box, z. B. in a special wash cabinet, possible ..

The nip 45 is preferably designed with an oversize in its length, so that when assembled color meter 26 this not end, d. H. with its the metering edge 27 opposite end abuts in the nip 45. In particular, this should not strike against a rigid, knife holder fixed path limitation in the manner of an at least one-sided positive connection, which z. B. would inhibit relentlessly any further movement into the gap with loosened traction. Below, however, for example, no yielding, z. B. spring-loaded or elastic trained Hinterkantenabstützung be understood which z. B. despite contact in the ready-mounted state of the color measurement 26 still no rigid form-fitting path limitation forms, but with open or relaxed form fit - for example, against the elastic force of a possibly provided support - at least slightly further movement in the nip 45 allow in it.

As a "nip" 45 can here in extension to the exemplified embodiment with an extension over large parts of the width b26 and with a cross-sectional actually substantially gap-shaped geometry in a broader sense, any expression of an arrangement of one or more pairs of opposing clamping surfaces be understood, between which the ink knife 26 is inserted and clamped. As "length" 145 of the nip 45 can be understood in this expanded meaning then that length on which the ink knife 26 with its holder-side end between the clamping surfaces in the knife holder 26 in

Longitudinal direction of the ink blade 26 without an end-stop on the knife holder 28. Missing a back stop entirely, so this length of the nip 45 would be virtually unlimited and thus in any case greater than required for a commercially mounted paint knife 26. This length, however, applies in the case of an in

Width direction extended or multiple pairs of clamping surfaces that length at which, when moving in this longitudinal direction at any point of the entire width b26 of the ink blade 26, a first striking takes place. This represents in reverse consideration so the length of an undisturbed insertion between the pairs of clamping surfaces.

The ink fountain 17 or its frame 23 may include on the ink roller 18 to be inked ink fountain side a front panel 52 which z. B. in turn can carry a seal, for example, of an elastic and / or compressible material. Furthermore, a traverse 56 may be provided, which in o. G.
