Invitations and invitations are roughly the same in function and content, but invitations are more solemn and formal. Invitations and invitations are also divided into commercial and non-commercial categories. Business invitations mainly include company business activities, celebration invitations, commodity promotion invitations, Expo invitations, exhibition invitations, etc. Non-commercial invitations mainly include birthday invitations, wedding invitations, mourning invitations and public welfare invitations. Invitations and invitations belong to small picture books, which are flexible in graphic design, size and layout, and can be designed according to different contents and requirements. It should be noted that both invitations and invitations have clear introductions and requirements on the time, place, invitees, invitation items and arrangement forms of activities, so the arrangement and design of these important information must be fully considered in the design of invitations in order to achieve a good visual effect of highlighting the theme and setting off the atmosphere.
