How to Create Geometrical Background in adobe illustrator.
Through using Gradient background, transparent gradient and few line (rectangle boxes) you can create geometrical background. You can add more shapes also, like dotted boxes and triangles. Adding balanced object will give you a good background. I make few more backgrounds with same pattern and color changed, check below.
Step 01 – Create a new file with “RGB color mode“, make a rectangle for gradient background.
> Fill gradient in background, you can choose color as per your choice, i create two more color options, which display at the end of the page.
Step 02 – Make a circle, fill gradient and make outer-side opacity 0% and Change shape.
Outer part transparent, also apply “Transparency Multiply“.
Step 03 – Decrease height of the shadow
Mask it: Create a rectangle above that cover only half lower part to mask it. “Object – Clipping Mask – Make“.
It’s view something like this.
Step 04 – Slightly rotate it, make more copies and place it on different part of creative. After that make a rectangle according to the document size and mask all layers.
Mask it also.
Step 05 – Create a gradient rectangular shape, one side transparent. Next step is to create highlighted bars which i make through another rectangle box, fill gradient downside yellow bright color and upside transparent gradient,
> Copy and place it multiple times in different parts. which reflect some lights moving to down from top.
Step 06 – Next step is to create sequence bars in background, which fill with gradient color. make a very thin rectangular shape and expend it according to the height of document, which covors full page, to make multiple copies of it i use, “Effect – Distort & transform – Transform“.
> Place it at absolute outside the document and apply “Effect > Distort & Transform > Transform“. Now you can make multiple copies of that line. Horizontal distance i give 30, you can change it also.
Cover it something like this.
“Object > Expend Appearance“, this will expend whole graphic, now you can click each line and edit if you want.
> Now its time to convert all of these line into a single graphic, “Object > Compound Path > Make“.
Step 06 – Now Fill gradient, gradient fill and treat it as a single object.
> Mask it also.
> This is the final output. Some other samples given below.
