The printing and publishing industry in the UK provides employment for about 200,000 professionals. Although the vast majority of the nation's 11,000 printing companies employ fewer than six workers, most in the field work for a large publishing house with a staff exceeding 200. It is estimated that the industry contributes roughly £10 billion to the economy each year, and London accounts for nearly a quarter of the overall market. Jobs in printing and publishing tend to be fairly relaxed and sociable, but hours can sometimes be quite long as deadlines approach. There are no standardised entry requirements in the sector, but most in the business possess degree level qualifications and backgrounds in design, literature, or journalism. Most training can be completed on the job, and employees frequently have the option to take professionally relevant courses during the first years of their employment. Ideal candidates will have a strong aesthetic sense, an eye for detail, and a meticulous nature. IT skills are also becoming increasingly important in the field. Salaries range from about £18-50K, depending on levels of experience and expertise. The overall average income for printing professionals in the UK is about £28K.
