Use Pantone Color In Adobe Illustrator

The PMS color or Pantone color is a standardized color matching system, which makes the accurate color printing possible on the custom paper boxes. The Pantone color printing is widely used for the brand names and logos of our clients. Sometimes, they are used for the specific texts and images.

However, it is a little bit tricky when our clients try to use the Pantone colors to create the artwork. They don’t know how to use the Pantone color in Adobe Illustrator. In this article, we will solve this problem by showing how to add a Pantone color to the Swatches window.

Step 1: Open the Adobe illustrator, and create a rectangle by using the rectangle tool;

Step 2: On the top menu, choose Window -> Swatches to open the swatches window;

Step 3: On the top menu, choose Window -> Swatch Libraries -> Color Books -> Pantone + Solid Coated. Then a window named PANTONE+Solid Coated will open as below with a search box on the top.

For the custom paper boxes, the printing is mostly done on the coated papers as SBS C1S, C2S, CCNB. We will usually choose the Pantone + Solid Coated by default. When a specialty paper is used, which is uncoated, we need use the Pantone +  Solid Uncoated.


Step 4: Input the Pantone number inside the search box on the top of the window above, the corresponding color will be displayed inside the window below. Here we would like to use the Pantone 801 C color.

Step 5: Move the mouse pointer to the corresponding color and hold the pointer there for a little while, the pantone number for the color will pop up.

If it is just the color that you need, just click this color. Once you click the color, this pantone color will be added to the swatches window for your easy pickup.  Then you can select the rectangle and fill it will this pantone color.

Step 6: Choose Windows -> Separations Preview. Then we will see the PANTONE 801 C listed in the Separations Preview window. And we can click the eye icon to check the position and effect of this Pantone color by making the color visible or invisible.

A4 Size Rigid Paper Box for Document

A well designed rigid paper box for the A4 size document papers can definitely make them more professional and high efficiency. Recently we made such a custom rigid paper box for a USA client. The box is usually referred to archive rigid paper box in general or archive paper box.

Works like a slipcase with the velcro closure

The cardboard archive box works like a slipcase. The office staff can easily slide the A4 papers inside and seal the box by the velcro closure  to keep the documents safe.

The velcro is 8mm in diameter, white color, which makes the box look very smart. The main advantage of the velcro closure is that it makes the box easy to open and close. Meantime, it keeps the documents safe inside without falling out.

Glossy laminating

Unlike most other premium rigid boxes with the matte laminating or soft touch finish, the custom rigid box uses the ordinary glossy laminating outside, which conversely gives the folder a brilliant eye-appealing effect.

UV litho printing

Compared with the traditional litho printing, the UV printing makes the color more crisp on the paper box. The color printing on the cardboard paper box is quite simple, grey background color with the orange color ribbon in the middle.

Besides the orange version of the rigid paper box, we also make a red version, which is more beautiful.

Rigidity and Strength of the archive box

3mm chipboard is used to make the rigid archive paper box, which is quite strong for the rough handling.

Grammage and Price Calculation of the PET Sheets


PET sheets/films are widely used in the custom paper boxes to constitute the clear window, also referred to the clear window paper box. In this article, we will talk about how to calculate the grammage and price of the PET sheets.

The density of PET is constant,  1.38 g/cm3 (20 °C). For a piece of PET sheet measured 100cm length * 100cm width * 0.1mm thick,

PET密度:1.38 g/cm3 (20 °C)。

volume =100*100*0.1/10=100cm3 ;

10丝PET克重(0.1mm厚度): 100*1.38=138gsm;



Therefore, theoretically the 0.2mm thick PET sheet has the grammage 276gsm;

The cost of the PET is usually priced at RMB14,800/t.






In theory, the per square cost of 0.2mm thick PET sheet wold be 0.6USD.

But in practice, a lot of other fees would be involved to produce the PET sheet. In reality, the per square cost of 0.2mm PET sheet is around 1.2USD.
