In offset printing, evaluating the cost of a raw material based solely on its purchase price can lead to a mistaken conclusion.

In the case of white ink, its impact goes far beyond the price paid for the product. An inappropriate specification for the application can interfere with print stability, increase the need for adjustments, generate waste, and compromise the machine’s productivity.

Therefore, to understand the true cost of a blank, it is necessary to examine its performance within the entire production process.

Ruby Carat. Because the true cost of a blanket should also be measured by the performance it delivers.

Price and cost are not the same thing

Two blanquetas may have different prices, but that does not necessarily mean that the one with the lower price will result in lower production costs.

The actual cost is also related to factors such as:

stability during the pull;
time needed to make the adjustments;
amount of material wasted;
frequency of operator interventions;
blanket durability;
need for replacements;
consistency in print quality.

When these factors are taken into account, the analysis is no longer limited to the product's price but also considers its contribution to operational efficiency.

1. Waste of paper and other materials

Every sheet of paper used during a new adjustment represents material, ink, and machine time.

When the transfer does not occur consistently, it may be necessary to make further corrections until the expected standard is met.

Individually, these losses may seem small. When multiplied by the number of jobs completed over the course of weeks or months, however, they begin to represent a significant cost for the printing company.

2. Machine downtime

A printer that is idle for adjustments continues to incur costs, but it is not producing anything.

The greater the need for interventions to stabilize the process, the lower the equipment utilization tends to be.

Therefore, productivity should not be evaluated solely based on the machine's rated speed. The ability to maintain stable and consistent production is also essential.

3. Instability during the pull

A good result at the start of the job isn't enough. Quality must remain consistent throughout production.

When the blanquette does not have the appropriate characteristics for a given application, variations may occur that require monitoring and further action.

This instability can affect both productivity and the predictability of the process.

4. Substitutions sooner than expected

Each application has specific requirements.

The characteristics of the press, the substrate, the speed, the pressure, the products used in the process, and the operating conditions can influence the behavior and durability of the blanket.

Using a solution that is unsuitable for these conditions can accelerate wear and tear and result in premature replacements.

In this scenario, an initial savings can turn into a higher cost over time.

5. Quality also has a financial impact

Quality issues are not just an aesthetic concern.

Reprints, discarded materials, delays, and the need for further adjustments have a direct impact on production costs.

The more predictable and stable the process is, the better the printing company will be able to produce according to expected standards and make better use of its resources.

Is the cheapest blanket really the most economical?

That's a question that can't be answered just by looking at a price list.

The best analysis takes into account the total cost of the operation.

A blanket suitable for the application can contribute to greater stability, better utilization of machine time, reduced waste, and greater consistency during production.

This does not mean that the most expensive solution will necessarily be the best. It means that the choice must be based on technical considerations and take into account the actual characteristics of each process.

Choosing the right one starts with understanding the application

There is no single ideal blanquette for all situations.

Therefore, understanding the equipment, the type of work, the substrates used, and the production conditions is essential for making an appropriate recommendation.

At Dugraf, our work goes beyond simply supplying blank sheets. We strive to understand each operation so we can recommend solutions tailored to the needs of each application.

Is your blanquette cutting costs or generating costs that you aren't aware of?

Evaluating process performance can reveal opportunities that are not apparent when the analysis focuses solely on the price of the input.
