Ink requirement and cost calculation. In this chapter is described how the required amount of ink for each colour and their related costs are calculated. This applies for estimate label calculation and job label calculation.

Where can you see the ink consumption? The calculated costs are visible in the 'Details of costs' overview of the label.

You will find the calculated quantities of required ink and the associated costs. These costs are added up to the other costs related to the label calculation. Printing surface The total printing surface of the calculation is determined by the total length and the minimum width that is to be printed for the label calculation.

This can be when:.

Ink coverage Of course, not the entire surface is printed with each colour. The ink coverage is indicated as a percentage for each individual colour in the printing colours of the label calculation. Net Ink consumption Additionally, one must know how much ink is consumed to cover the calculated surface. This default ink consumption can be overwritten with a specific ink consumption for a colour on a label press. If this is the case, this specific ink consumption will override the default ink consumption.

Extra Ink consumption Exceptionally, an extra ink consumption percentage can be indicated in the paper type. If this is the case, the extra ink consumption is added. Note: in case the same colour is printed multiple times, this extra ink consumption is counted only once! Fixed ink consumption If a fixed ink consumption is defined in the label press parameters, this quantity will always be added on top of the net requirement calculated so far for each colour.

This default fixed ink consumption can also be overwritten with a specific ink consumption for a colour on a label press. Note: in case the same colour is printed multiple times, this fixed ink consumption is counted only once! Minimum ink consumption If a minimum ink consumption quantity is defined in the label press parameters, the calculated required amount will be raised to this minimum quantity if it is lower.

This default minimum ink consumption can be overwritten with a specific ink consumption. Note: in case the same colour is printed multiple times, this minimum ink consumption is counted only once!View E-Clips Archive. Subscribe to E-Clips. Almost every day I receive questions relating to ink or coating thickness determination. You would think it would be a simple matter, but it is not. It can be confusing.

It's almost like everyone is speaking a different language about the same thing. The amount of ink deposited on a substrate depends on the ink formulation, the printing process, and the substrate. You normally have to carry more ink on a porous substrate compared to nonporous substrates to get the same color density.

In practice, the actual ink thickness rarely is measured. Print reflective densities are used to put the desired ink level on the substrate. A common measure of ink thickness is in units of microns. A micron is 1 millionth of a meter. In practice, however, it is not easy to determine the thickness of an ink in microns directly. The amount of ink on a substrate often is expressed in terms of weight of ink per area of print. A ream can be any size, but it is common in flexible packaging to use dimensions of 3 ft wide and 1, ft long, or 3, ft 2.

The different printing processes deposit different amounts of ink. Lithography is estimated to deposit an ink film of approximately microns, whereas flexography's deposit is estimated at microns. Rotogravure can have a wide range from microns, depending on the cylinder etching.

Achieving accurate ink thickness depends on the type of substrate. For instance, printing of paper presents some special problems. The paper surface can have significant surface variations and require more ink per area to assure it has the required reflective densities and surface uniformity. Ink penetration of the paper makes accurate ink thickness measurements difficult. The reflective optical density is the most convenient method of estimating the amount of ink on a substrate, but it has accuracy limitations at high ink densities and with certain pigments.

For coatings or inks with high transparency, optical methods can be used. One of the more accurate ways to determine the amount of ink on a substrate is to look at it from a side profile using high magnification. The trick to this technique is to get a printed sample and then fracture it at a very low temperature liquid nitrogenwhich allows for a side profile that can be viewed.

This method depends on having one or more detectable metal ions in the ink and knowing their concentration in the ink formulation. Richard M.

This calculator determines the amount of ink you will use given the variables entered, including percent ink transfer. It does not take into account anilox condition or metering effectiveness.

The variables above are all that a narrow web shop needs to use. You do not need to worry about repeat length, gear size or pitch, or anything like that. Enter roll length in feet in the Quantity of Labels field. See Table below for help with individual fields and what should be entered. Total quantity of labels that you are blending this color for. This includes any planned over-run for waste, etc. The minimum amount of ink that the print station needs to operate properly.

In theory, you need to blend the amount of ink that gets consumed, plus the amount of ink that is just barely enough to keep the system flowing smoothly.

Fabric Weight Calculation in GSM

An anilox roll does not release all of the ink in its cells. It only releases a percentage of it. After that, the plate only delivers a percentage of the ink that is delivered to it. Therefore, the actual amount of ink being transferred to the substrate is a percentage of the theoretical anilox volume.

You may know this figure based on historical ink consumption. Adjust the value for percent ink transfer in this calculator as you use it, over time, to more closely match your actual conditions. Note: There may be a situation, such as with two-roll systems, where the ink transferred is actually greater than the theoretical volume. However, these cases tend to also result in variable ink consumption rates. Percent of area of the label that is covered by the color you are calculating consumption for.

Color Printing Forum. Offset Printing Calculation for ink Joined: Nov Messages: 8 Location: Delhi. Hi friends This is Sonu Kukreja Can u plz tell me the way or the procedure to estimate the quantity of ink required to print Color Processing or Pantone Color Processing.

And which are those factors on which this quantity depends I will be glad full to you Joined: Jun Messages: Location: uk. Your ink supplier will have figures but its only an estimate. There are many other factors that come in to play when using the ink which make it impossible to measure.

DataNov 1, Dear Thanks for ur valuable reply. But i wanna to ask Is there any standard formula to estimate the quantity of ink, that can help me to estimate the cost of printing. And how does the temperature affect the quantity of ink required to print the document. And does the change in temperature affect the quality of the product to print and does the gsm of the paper also affect the quantity of ink.

Thread starter gjk Start date Sep 22, Does any one have any idea how actually the Ink used is calculated wrt the area of coverage on the layout. D Ink Man Well-known member.

Here is the most simple I believe the beast for lithographics inks: This has been utilized for many a moon now. Here it is. This is a tried and proved simple method. Of course you will caculate the coverage based on solids, halftones and size of the printed sheet based on the above caculations.

Keep in mind, higher specific gravity inks, such as metallics will use more and lower specific gravity inks with low pigmentation will use less.

This is a basic generalization.

Try it and see what your current mileage estimate comes out versus any other caculation you might use. I believe that once utilized on multiple estimates, you might thank me one day. Last edited: Sep 22, I will agree with D Ink, If you figure the total area sq in of solid printing then multiply that by total impressions, then divide that number bysq in per pound of ink will give you a estimate of ink needed. The pound per square inch is the biggest variable.

You may getsq in from a pound of ink, but on the other hand you could get onlysq in per pound. Ink Usage calculation based on coverage area It seems to me, being a student of ink usage There are multiple factors that must be considered.

The factors mileage per pound of ink are significantly different. This should be a key element when figuring ink usage. I am currently working with Prinergy and there are capabilities in the engine of generating an ink report when we impose our files and send the CIP information to press.
